I know it's nothing amazing I came up with but I always wondered why people can't just all go when the light turns green. They sit still until the car in front of them is 30 feet gone. Drives me fucking insane.
The other bit is when you're getting shat out of the snake FUCKING GUN IT. I feel like people are lulled into a sleep and are afraid to accelerate out the snake like, "It's a 70mph freeway but I was crawling for the last 20m, better go 45mph for a half mile or so to ease into this."
