I had never been in an accident in 22 years of driving a vehicle until several months ago when I was rear-ended while sitting at a red light, in bright, mid-day, dry conditions. My car was the only one at the light even. This extremely poorly driving (or distracted?) human is presumably still out there on the roads somewhere.
