Road rage

I was walking my son in his pram for his afternoon nap and saw an ambulance (not in a hurry) coming down the street, side swiping a car, then getting jammed against it, reversing to free the ambulance from the parked car and then driving off, full in the knowledge that they had hit the car and, that I had seen them. Luckily, the driver appeared shortly after and I was able to inform her and give her the licence plate. Does anyone else see stuff like this, does anyone else think that some people tear down the street at a dangerous speed?
