B, you can be 'anal' about being as safe as possible, but, on a bike, you can't always foresee the situation where somebody will take you out.
You can overcompensate for every jerk out there, and you'd probably never get anywhere. Being cautious will tilt the odds in your favor, but there's no way you can eliminate paying some price for the stupid or reckless habits of most drivers.
I had a situation like yours, where the car never actually touched me, but sped past me at 45 mph or so when running a red light.
I had the green light, and essentially dropped the bike in the middle of the intersection while trying to avoid the red light running car.
I was lucky in that situation since I wasn't hurt, it was daylight, and got on my feet right away in the intersection and motioned at the car to come back....and it actually did!
(The next step if it hadn't turned around, would have been to quickly evaluate the damage, determine if the bike was operable, stand it up, and chase the biotch down! Since we were about 2 miles from the state line, it could have gotten interesting.)
The fact is, we don't HAVE to ride bikes. If you're uncomfortable riding the bike after this, it's no big deal. There's no macho factor. It happens.
I sometimes try to analyze stupid traffic habits until I get crossyeyed!
I found it easier to just not ride in such conditions, if possible.
