Deliberate mistake: The relay drag race takes much longer to complete than it should. Each leg is a quarter mile going and back, the cars involved should be able to make their runs in much less time than is shown. Brian even tells Roman that the Yenko (the blue Camaro) can do a quarter mile in 5 seconds flat, but it still takes ten times that long to complete the entire run.
