I generally drive a very lowered classic car (it looks better lowered), and beside the fact that I tend to cruise slowly around rather than rush around when driving, I have to drive over speed bumps at a extremely low speed. It seems to infuriate drivers behind me who speed up to the bump then brake hard then speed off. In the end they surely never get where ever they speed to before I would get there in a more relaxed manner as with traffic lights, traffic and speed bumps we are surely slowed down in the same way anyway.
