When everyone arrives at the airport, the green taxi pulls in behind Henry Fonds's convertible, which pulls up to the front of the yellow taxi. Moments later, the taxi driver arrives on the motorcycle. He hits the back of the taxi and flies over it, but the other cars are not there.
While on the chase to the airport the road they are driving is normally 2 lane in each direction road being used as a four lane highway. You can see the double yellow line in the center that divides the normally opposite flowing traffic.
