So, as a little kid I remember 2 movies in the same vein: The Cannonball Run & The Gumball Rally. Both were entertaining, but I've not seen either for years (decades probably). In the 90's I actually did a ton of IT work for one of the actors in The Gumball Rally over the course of a few years - Walter Smith. He played the policeman and had a few lines, mostly cursing if I recall (which fit him well) - he was quite gifted at it.

I need to revisit both movies to see how they hold up.

The only thing I remember about the movie is that my favorite car at the time (Chevy Corvette), wrecked and split in half just after a minute or two into the race.

I'm not saying that its not dangerous to others, but the only thing I can compare to is when I visited Wyoming a few years ago. I flew into Casper since it was cheaper and drove across the state to Cody. Don't know my average speed, but I was over 100 much of the drive. I slowed down for the occasional town or two and anytime I had to pass a car of course, but on the open road I could literally count on both hands the number of cars I saw during the drive (I don't remember the day of the week, but it was mid-day). When you're out there in huge open expanses all alone, you don't even feel like your going that fast.
