Always have an escape route
10+ years ago. As I was going along, the truck in front of me stopped suddenly with plenty of room ahead of him. He shouldn’t have braked so severely. I perhaps could have avoided it by going slower but his severe braking was unexpected. When I go by him on the right you see there was plenty of space ahead of him too.
The video was supposed to show that going down the very right lane often is the fastest in rush hour, but it ended up showing you need to always have a way to escape.
