Sorry Paddy, call me boring, but I don't see anything to laugh at in this at all. It's not funny if it causes another driver to swerve into the path of a truck and get mangled, is it. Antics like this cause innocent people to get killed, while the idiots that cause the mayhem disappear.
Stunts like this are fine if they're performed by stunt drivers and confined to the movies, not on public roads. I think both drivers should be locked up.
