The Gumball 3000 is a semi-legal international street race that has been happening every year since 1999. It’s wikipedia page goes out of it’s way to make the race sound legal, and if one were to only see their start and finish lines that would certainly appear to be true. Watch the videos though, and you’ll see things getting fantastically criminal in-between.
This is amazing.
(Even KITT from Knight Rider has participated in the rally.)
