Favourite has to be W - Two Worlds just as you said. I love the meta of it appearing in a kdrama about a manhwa and it's pretty plot-significant because Kang Chul realises the external control of his world in that moment.

Another one that I probably wouldn't call 'favourite' but was definitely memorable was the one in Shut Up Flower Boy Band. Let's just say that one hit ME like a Truck of Doom. I really should have read the recaps before I started 😓.

Least favourite would be pretty much most of the others with the most recent, and egregious, example being in Why Her?.

🍿🍿🍿

1. - Moonshine. Who knew a Truck full of Joseon's freshly brewed finest alcohol could audition as a ToD? More interesting was the bad guys getting a taste of the very alcohol they've been gunning for before they remembered they're supposed to chase after our heroine and co.

Honorable Mention
Extraordinary Attorney Woo ToD on the jerk husband in episode 11.

2. - Vincenzo episode 3 ending. ToD attack on Hong Yu-chan(Yoo Jae-Myung). This one hurts to the bones.

3. - Vincenzo.
It was the act that forced Hong Cha-young to move to the other side of the law - her father's side. Babel shouldn't have hurt her father if they wanted to keep their reins on her. But, they ultimately miscalculated, and it spelt the beginning of their doom from Hong Cha-young's end.

Honorable Mention : You're All Surrounded ep 19. ToD attack on Police Chief Kang.

4. - The ToD in Why Her is the first on the list for now. Oh Soojae will still 100% act the way she acted(as alleged by the ToD) without the ToD. There was exactly no need for it, and the casualty wasn't it at all.
Why Her?, take a lesson from #3. subsequent shows, kindly do same.

The two dramas that immediately come to mind are Dear my friends and Devilish joy where it was crucial to the love story.

My first encounter with the truck of doom was long before I knew about Korean dramas it was in a film called One day so I saw it at the cinema and it has left me traumatised ever since. I always get shocked by it and think it’s an awful plot devise. I prefer a car crash with people in the car rather than being hit while walking or riding bike. I work in a University town where bikes are everywhere and I am hyper aware of them now.

My most recent one was in Atty Woo and i have to say, I didn’t expect it from the drama at all. It was almost like a surprise cameo.
I wonder if @ToD is still around on DB?

It's crazy that everytime a character is on a pedestrian crossing, I have fears.

In Shut Up Flowers Boys Band, I wasn't surprised because I knew that LMK wasn't the ML, but it was kinda funny how they filmed it.

Do Min-Joon could make a fortune by saving every character from the truck of doom.

My favorite would have to be in Switch with the double Truck of Doom.
The ML is just driving along suddenly sees a truck coming towards him, barely misses it, and then WHAM! Another truck comes from behind the other and slams into him pushing him off the cliff.
Very exciting and it is the set up for the whole drama because ML is injured in the car crash so his coworkers find his doppelganger who happens to be a conman and get him to switch places with the ML prosecutor.
Honorable mention:
The Great Show. ML (politician) has taken in four kids. One of them runs in front of a bus to get a toy that rolled out into the street. ML runs in front of the bus and to try to protect the boy, and then you see ML fall over when the bus hits him. Turns out the bus actually stopped just short of hitting him though and he was just putting on an act so he'd seem more heroic and get good press! 😂
Least favorite: A Poem a Day
Technically a motorcycle of doom but why'd that motorcycle have to come out of nowhere and hit my boy Minho when he was on his way to confess to Boyoung??? 💔😭

I'm not sure if this counts, but one ToD that I thought was really interesting was in Oh Hae-young Again. The ML has visions that he eventually realizes are happening because there is some funny timeline business going on, and really he's just been hit by a car. But the circumstances of the accident get illuminated slowly and change throughout the show as he sees more and then makes different decisions. I don't think this is my favorite or least favorite, but it was definitely one of the more interesting ones I've ever seen.

The ToD on Vincenzo was only the second one I ever saw, but I thought it was used well, and pretty tragically. It had the classic hallmark of a ToD, in that it came out of nowhere, but didn't happen when someone was crossing the road, so for me it remains one of the least expected I've ever seen. And then Vincenzo uses a potential ToD to threaten the baddies later, and the baddies use another one to kill off an innocent man, so this drama might set some records in this department.

A TOD that worked to put the final exclamation point on a twisted story was in THE BABYSITTER - - - unexpected, shocking and a story flip on the viewers. (I just re-watched the series last week)

Word of advice to relatively newer beanies. This post is probably full of spoilers.

ToD played a key role in Hello Me!

It also played a key role in Thirty But Seventeen. In that drama, the driver actually also played a role.

And ToD played an offscreen role in Remarriage and Desires. A non-accidental role....

I'm trying to remember a drama where the ML or FL was a child driving with parents and the car was crushed by a ToD, only the kid survived. What drama was that?

Untouchable: It's used twice throughout the series. ToD made his first appearance killing off the wife of the ML who is a cop. Later it's used to kill off the Ml's older brother while he pushes his wife's car out the way while she's trapped inside and then witnesses her husband being ran over.

least favorite(s) = Shut Up Flower Boy Band & Meet Joe Black

I love it when it takes out a bad guy so the drama doesn't have to spend time on him. Like in Sell Your Haunted House with the stalker dude who killed a woman. The good guys were already chasing him through the alleyways and right when you think he was getting away...he got TODed.

I liked it in Extraordinary Attorney Woo too. It was so tough on the wife to see the doting husband turn on her overnight, so I'm glad she was spared the divorce proceedings. That wife worked so hard and you know that husband - even if the divorce goes through and once his money runs out - is going to come back to harass the wife.

One of the saddest uses was in Fated to Love You.

I think the worst use was High Kick Through the Roof. I didn't watch that sitcom/drama, but I remember when that ending came out and the fallout...

Anyone who has watched that drama and went through it...I think they can do through any terrible ending.

What really bug me about truck of dooms is that they usually don't follow up with the drivers when the drivers aren't evil henchmen.

Does the Cliff of Doom stand in for Historical dramas?

Trucks of Doom. TODs. Even my friends who have never seen anything Korean know what TOD stands for because I’ve talked about so many. It annoys me that even after all these years I can feel my blood pressure tick up just at the sight of a crosswalk.

Nothing beats the double ToD in About Time.
People often criticise ToD for their performance, suggesting their narrative input is often too broad and a little cliched. This despite all their hard work across multiple dramas.
But they truly did a public service in About Time by taking out both those assholes at the same time.
If only the deaths had stuck.

I'm actually a big defender of the TOD in SUFBB. Not specifically because it's a Truck necessarily, but because I like how they used a plot device death as a catalyst for the rest of the show. I've written about this better somewhere else before, but I liked that Byunghee isn't forgotten after his death, and turned into this empty plot device character that so many other show's would've done, but rather the weight of his death is felt and continued to be felt throughout the whole show; indeed how the other boys deal with and react to grief is one of the main thematic cores of the show. I like that this event sent them all reeling, aimless, directionless, and now they have to pick themselves and the pieces up afterwards and find their new directions and loves in life without this core piece and person that was so integral to them all for so long.

However, I think it's a shame that such an infamous TOD causes so many people to drop it early, because I think they miss out on a really good youth drama that has a lot going for that isn't just Lee Min Ki in eyeliner.
I knew Lee Min Ki was a cameo going in to SUFBB, and I think that really helped mitigate the death somewhat- because I knew he wasn't going to be around for the whole thing- which is how I would recommend going into the show now as well.
I'm not usually a fan of such catalyst deaths, but I think they handled it and dealt with it really well, and as such can only continue to recommend and love the show.

Not a kdrama, but there was a TOD in the movie Last Night in Soho and it was equally as dumb and only there for cheap shock factor as many a kdrama TOD, and I got just as mad as I would've in the best and most contrived kdrama scenario.
What @sincerelytod was doing in my dumb Edgar Wright horror movie, instead of Ed making another horror comedy movie with narry a cheap jump scare in sight, I do not know.

OH MY GOSH HOW COULD I FORGET. Letting myself down!

No, no first prize HAS to go to Secret Lyfe of My Secretary, with its ABSOLUTELY unbeatable batshit bananas Truck of Doom, because it created the FISH CULT!!!!! The infamous og Fish Cult! Which caused the whole drama!
I will never, ever make a drama prediction as good as that ever again, probably.
It was all the fish's fault!
Imagine dying by TOD for a FISH! And then a Fish Secretary Cult is created in your memory and honour! To launder company funds for the sake of fish Orphans! And the rights of fish Secretaries! And our ML gets magical fish face blindness that kick starts the entire mystery around the Fish Cult and also our OTPs fishy lie laden love story! And then the fish is replaced with a fake fish! And the lack of the Fish leads to the Moss Balls, which are the main wingmen for our OTP! Wow. What a TOD. What a fish. Legendary.

When it comes to TOD my mind just blanked out fr even tho I saw so many over the years that pissed me off (i think thats why I blanked out theres too many for me to decide)
I think it would have to be those TODs that just have zero correlation to the plot (or used as a desperate last minute resort to tie the plot together) that turns me off but thanks to all those, I have training to anticipate any upcoming TODs in current dramas (the way my anxiety soars when its night and the lead(s) are on a road)

But could we also have an amnesia drama chat thread too? I know of a few that disappointed me to the core hehe

Favorite ToD: the one that doesn't work - the person only gets hurt or is saved by someone (aka. the least annoying result).

Least favorite: the one that doesn't appear when you want it (aka. when the bad guy is the one crossing the road).

I did a quick scan down the comments and was surprised Goblin hasn't been mentioned. That one genuinely upset people.

The very first truck of doom I recall (and one of the most impactful) is pre-Kdrama watching days for me. 2010, the dump truck T-boning the sedan in the film 'Man From Nowhere'.

An unusual recent role for the Truck of Doom is Truck of Doom as The Hero: In episode 11 of EXTRAORDINARY ATTORNEY WOO the White Truck Of Doom saves the day by delivering just deserts to the ultimate jerk of a husband.

Oh I suddenly remembered a TOD that shot a man who wished to stay anonymous to national fame and hero status. Pinocchio.

The one I correctly predicted while watching Start Up. Hubby walked in the room asking how the show was doing. I replied, "About time for the ToD." It hit the inventor dad two seconds later. We both shouted woah.

I tend to appreciate the truck of doom trope. more when there's a twist, such as folks have mentioned with W's meta moment and with the divorce-seeking jerk in Extraordinary Attorney Woo. Another twist example is Goblin, where the female lead makes a calculated decision to save a group of young children from the TOD, and looses her own life in the process. There are plenty of KDrama leads and second leads that end up getting killed or injured saving one person from the TOD...not so many that end up saving a whole bunch of people.

Yknow what would be funny & still make sense? Some school or crime drama talking about rising numbers of accidental deaths due to improper road crossing, & some rebellious kid or drunk ahjussi being all this is nonsense & jaywalking & then getting hit with TOD. Ofc in this case they'd be a crucial character or witness of some sort so their death would leave a mark on audience, teach some morality & serve an actual purpose besides just killing people with shock value.

Also never expected to see a thread asking about our fav ToD moments.... Colour me surprised 😲

I am wondering what the truck of Doom does on its day off

Shut Up Flower Boy Band.
It was both the most memorable one and my least favorite one. It was unexpected, devastating and powerful.

If we’re going to talk about danger tropes, how about also doing a thread on the booty scoot? You know, when a person is running away from danger, predictably falls, then tries to flee by 1/2 crab walking backward and 1/2 scooting away while dragging their bum on the ground.

Or the one where a person is being choked and instead of using large muscle movements to break free (or kicking them in an unhappy place), they just clutch the person’s hands while pointlessly scraping the ground with their feet.

Or the one where a person is in an accident and the first thing the onlooker does is cry while shouting the person’s name for about 5 minutes. Then - instead of doing something wacky like calling 119 or administering CPR - they flip the potentially spinal injured person over so they can cradle them while crying some more. 🤦‍♀️
