Noticed interesting things on the bus today
How to say thank you on large vehicles? On Greyhound, you use temporary warning light (the red triangle button, don't know what it's called)
On tractor-trailer, apparently they use 3-short-burst brake lights to thank the vehicles behind them. I find them clever and amazed at Canadian's politeness :) (Not for young drivers though, I so want to teach them proper manner)
However, it is awfully dangerous, when the driver was one-hand-driving while talking on the phone, couple hard brakes!!

Another interesting thing is, Greyhound's driver seat "floats" as the bus drives over bumpy roads. It's so funny that I just see the driver bumping up and downs with the roads. Is it possible for him to "bump out" of the seat, given a LARGE hole on the road?
