Almost car accidents...

Have you had any hear misses lately?
I had one just now.
I am waiting at a T Junction road, red light.
Light changes to green car in front of me goes, I go.
As I am turning, a car comes through the intersection, against the red red and I mis t boning him by about 1 foot.
He obviously was not paying attention and drove through the intersection as if he had a green light.
I only gave him two toots and we continued on our way.
Concentration is needed at all times whilst driving.
