Alice wants Bob for something, whether because she wants to talk to him face-to-face, kill him, or she's just leaving and is looking back over her shoulder. Suddenly a bus or large truck comes out of nowhere between the two, and in the split second it takes to pass, Bob has mysteriously disappeared.
This may happen when Bob is apparently not looking, and therefore wouldn't know when to duck out of sight; alternatively, Bob may be standing there, grinning and staring at Alice, right before he disappears. It might be revealed that Bob latched on to the speeding vehicle justifying this trope.
If Bob really wants to show off, he'll do this with a single person walking past, rather than a vehicle.
Related to the Stealth Hi/Bye, but with large noisy wheeled props. See also Train Escape. If the vehicle itself vanishes, that's Dude, Where's Our Car?. A child-themed sister trope is Carousel Kidnapping.
- There's a match.com advert where a man is singing to a woman on the opposite platform at a train station. A train passes, and when it has gone past, she's gone. He begins to sing again sadly, believing he'll never see her again, when he turns his head and she's sitting next to him.
- There was a similar commercial for beer: A group of young people are sitting at the railroad station in some remote town out west. A train races by, and through glimpses between the cars a strange young man in t-shirt and jeans is spotted on the other side. After the train passes, he crosses the tracks, introduces the group to the pleasures of the brand-name beer, and after a few moments returns to the other side of the tracks, where another train rushes by; again he is glimpsed until the second train has passed, revealing... nothing.
- Somehow, Jiyu's comic relief friends do this with a train to get her away from her Dark Magical Girl Counterpart (after being beaten soundly) in the second episode of Jubei-chan season 2.
- This occurs in the first scene of Eden of the East, where the main character uses it to elude a police woman after grabbing her attention away from Saki, who was under suspicion due to having thrown something over the White House fence (a coin).
- Used to heart-wrenching effect in the Bittersweet Ending of 5 Centimeters per Second: Takaki and Akari (or someone who looks like her, or even an outright hallucination; it's never made clear) walk past each other at some train tracks. He turns to look just as a train goes past; by the time the train clears, she's gone. Earlier on in the third act too, there is a shot where Takaki is on his computer at home, a wind causes a curtain to obscure him for a moment, and he's gone when it settles down.
- Subverted in Neon Genesis Evangelion: Shinji quits NERV; Misato shows up just in time to see the train he has (presumably) boarded pull away. The train departs; he does not.
- Hell Girl did this frequently with Enma Ai.
- A subtle variant occurs early in Ah! My Goddess: The Movie, where Morgan has her back to the camera and is looking at some posters, passing students block the camera's view of that student, and Morgan is gone. This varies in that Morgan isn't actually trying to hide or shake pursuit, and hasn't even been properly introduced yet as a character.
- Subverted in The Pet Girl of Sakurasou. Sorata shouts a Love Confession to Mashiro as the latter's train pulls in; when the train leaves, she's gone. But a few seconds later, she comes running down the stairs to meet him.

- The Trainman disappears behind a train this way near the beginning of The Matrix Revolutions. Justified, as he's a computer program that runs the virtual train station, giving him nigh-omnipotence.
- Subverted in National Treasure (1:19:52). Nicholas Cage is being tailed by the villains. A bus passes in front of him... and when it's finally passed, we and the villains both see him high-tailing it.
- Played straight earlier when Riley is waiting for a kid he's been bribing to write down specific letters from a museum display. Ian is in the museum as well and sees the kid writing down individual letters, which he knows are for a clue. In the meantime, Riley saw what he was writing (now in full) inscribed on the Liberty Bell in an ad on the side of a bus. By the time Ian and the kid run outside, the bus has passed and Riley is gone.
- In Spider-Man 3, Peter leaves a confrontation with Harry in a diner, then once he's across the street, glances back; Harry gives him a sinister smile, then a truck passes and Harry is gone from the diner. How he achieved this is unclear, as there's nothing in his goblin powers that suggest super speed. Perhaps he just ducked under the table?
- In Billy Elliot, Billy's friend vanishes like this after they have a conversation. A strange use of this trope, as it happens randomly in the middle of a gentle family comedy about a boy's dreams of being a dancer.

- Reversed in a scene from Killer Klowns from Outer Space with a little old lady sitting alone on a bench. A bus passes through the shot in front of her at full speed. When the bus is gone, one of the killer klowns is mysteriously sitting beside her.
- Clint Eastwood in The Western Pale Rider does this with a train, one of several Stealth Hi/Bye scenes that suggest he's a supernatural figure. However the train is moving slowly so there's plenty of time for him to have simply ridden away, leaving the whole question ambiguous.
- Like so many other tropes, 1941 takes this to the extreme with three Vehicle Vanishes in a row, one of which we see from behind the vehicle, demonstrating how the trick works.
- Superman. This happens from the point of view of the cop following Otis. He sees Otis on the other side of the rails, and after the subway passes by Otis has disappeared.
- Clever variation in The Living Daylights - a KGB agent has Kara under surveillance. He watches her enter a phone booth, then, after a streetcar lumbers by between them, a black Aston-Martin parked nearby drives off. It takes the agent a short while to realize she'd put her hat and coat over a cello case in the booth and gotten away with Bond in the car.

- The Bourne Identity
- This is the first sign that Bourne is more than he seems. When he's leaving the boat that found him, he vanishes behind a very small car passing between him and the camera. You can clearly see him running ducked behind the car for a few frames before the transition.
- Justified Trope during the car chase in Paris. A police motorcyclist is pursuing Bourne's car by driving along a parallel street. A large van obscures the car for a moment, only for it to vanish. The policeman is craning his neck to see where Bourne went when he collides with another vehicle. The next shot reveals that Bourne had turned down a side street.

- Juncture: On the el platform in Chicago, Anna sees her first victim sitting on the bench on the opposite platform. He stares at her, and then vanishes as a train passes between them. Justified as he is just a hallucination brought on by the tumor in her brain.
- In Tea with the Black Dragon by R. A. MacAvoy:
She stepped into the street. A bus pulled into the crosswalk behind her, concealing her from Mayland Long's sight. A black Lincoln stopped at the corner parallel to her path, then turned right into the crosswalk.
The light changed as Mr. Long reached the corner. He raised his eyes over the roofs of the cars, seeking the blue dress along the next block.
She was not there.
- Lampshaded and Averted in The Astonishment of Haruhi Suzumiya:
As though the future was flashing before my eyes, I felt a sudden conviction that when the train had finished going past, Kuyou would no longer be standing on the other side of the line. Somehow she would be standing right behind me instead, reaching out her pale, ghost-like hands...
A terrible delusion. The train went past. The red warning lights, relieved of their duty, stopped flashing. And the black figure of Kuyou was standing, as ever, on the other side of the gates.
- Played with in the Discworld book Night Watch. Vimes spots one of the History Monks, who have a habit of disappearing when he tries to get information they don't want him to have, from across the street.

- The Punisher (2017). Deliberately invoked in "Two Dead Men", when Frank Castle waits until a truck passes between himself and where he thinks Micro is watching him from the roof opposite.

- A more dramatic example than most, but during the Second World War, the tram that always made rounds in front of the Dutch Theatre in Amsterdam (Hollandse Schouwburg) would unknowingly fulfill this function. People who were to be deported were called and grouped to be collected there, but everytime the tram stopped in front of it, the guards could not oversee them for a very small timeframe. This proved to be enough for some very brave people to 'smuggle' children to safety and hide them in the school that was at the other side of the road.
