Race

Well there's too many goofs to mention, but my biggest is they cross the Hoover and cruise around the desert. Unless they had crossed earlier and what we see is the trip back, then they wouldn't have headed back to Vegas unless there's a Dow stream crossing I'm not aware of. I know driving semi there years ago it was the Hoover or a long way west before another crossing.

I also like the fact that they put in an engine they've never tried to a car he designed but never had a racing engine, and then they race and win as is without needing any tweaks.

My favorite though was the Flintstones sound effects for the cars. Now that was really funny....Especially the skid to a stop...
