Yen-Che street cars

The Yen-Che street cars are a group of background vehicles featured in the 2008 Speed Racer film.

Background
Three cars sponsored by Yen-Che can be seen at the Casa Cristo 5000 rally race. One of them, car #96, is driven by Scooter Dickey. They drive aggressively, although they likely weren't hired as headhunters by Cruncher Block like some other drivers, as they can be seen trying to take out Sempre Fi-Ber team members as well.

Car #90
Starting on the fourth row, this Yen-Che car drove under the number #90. After originally planning to go left lane, the driver then shifts back into the middle loosely, almost colliding into a Joe's Drive-In car. He then breaks back into the left lane when the driver he cut off tries shunting him back for it. He gives Taejo a little shunt which makes him pull away. Speed catches up to him and car #90 tries to jab him from the right but Speed dodges it and pulls away from him. After the Shark Driver misses Speed and wrecks, it puts the Yen-Che car in a nasty situation as he's pelted with debris. To avoid it all he shifts a lane right and loses his position as a result. He makes it out of the Muqranna but falls behind his teammate in car #99 for the rest of the leg.

In the Second Leg he is seen with the Yen-Che Team behind Speed, and they stay there for the rest of the leg. They never pose a threat. Glimpses of the team can be seen starting at the hill turns and traversing the ice mountains. Both times being far behind the rest of the pack, and it is unknown if they finished.

Car #96
Starting on the fifth row, this pink and yellow Yen-Che Car has the number #96 on it and is driven by team leader Scooter Dickey. In the Muqranna the car can be seen swerving into the middle lane in front of Racer X. After that moment it isn't shown for the rest of the segment but the #96 can be seen a few times in the Zunubian Desert. He is first seen there when he hit one of the Sempre Fi-Ber drivers, causing them to tumble out, but thankfully stayed in the race. He can also be seen dodging a spinning Speed Racer. Despite not being shown for the rest of the leg, #96 does complete it.

In the Second Leg, he appears with his team, but behind the main contenders, and he stays there for the duration of the race.

Car #99
Starting on the second row of the Casa Cristo, a Yen-Che driver driving a green car with a yellow #99 can be seen. He gets a good start, almost catching Snake Oiler. He takes the right lane and stays in the front of it for most of the Muqranna, avoiding other drivers. He also exits the Muqranna with ease, but behind Team Taejo. In the beginning of the Zunubian Desert we can see car #99 following the trail behind the Thor-Axine leader. Car #99 can also be seen trailing behind the Sempre Fi-Ber team on the dunes. While Speed is getting attacked by the Flying Foxes Freight team, car #99 is seen in the background going wheel to wheel with cars #24 and #27 from the Atomic Injectables team. Him being so close to Speed almost is his demise though, as when Speed lost his tire and was sent spinning, he almost crashed into #99. Thankfully for the Yen-Che driver, he managed to swerve left and avoid the hurdling car. Despite this close call, the Yen-Che driver managed to finish the first leg of the Casa Cristo.

In the Beginning of the Second Leg, the car #99 was close behind Team Taejo. However, as the race went on him and his team began to fall behind, by the time that the lead contenders were fighting, it was already too late for the Yen-Che team to make their move. Glimpses of the car can be seen starting at the hill turns and traversing the ice mountains. Both times being far behind the rest of the pack, and it is unknown if they finished.
