I was walking down the street to my house because school had got out early.  It was moderate traffic, light for those who live in big cities, and I heard PBOw, saw a red jeep-truck-thing go up onto the curb about right across the street from me, and hit a tree.  The air bag exploded immediately, and there was a loud pop when the car hit the tree.

It truly wasn't as violent or noisy as I expect most car crashes to be.

Apparently, the man inside the car had had a sugar attack because of diabetes, and he was not injured, at least not enough to have emergency services help him out of the car and walk on his own to the ambulance.  Several people. including some servicemen working at a tire shop and a motorcyclist, walked across the street to help the man.  Emergency services, including a cop car, two cop bikes, a fire truck, and an ambulance arrived on the scene in the space of two to five minutes.

This was the first time I've ever unconsciously put my hand up to my mouth.

No one was killed, and apparently no one was seriously injured.
