Attacked

The best thing to do is to just not put yourselves in positions where a drivers mistake is likely to cause you problems. This means looking over you shoulder all the time, knowing when to overtake buses, staying clear of car doors, not tailgating, having a good brake + therefore being able to stop your bike very quickly, and just generally being a good rider.

You'd crash into a lot of stuff looking over your shoulder all the time.

I am a good rider. I am a safe rider. I spend enough time on the bike though that I will encounter trouble at some point. Case in point, every second week during a club run some fucko feels compelled to force their car past the bunch on a blind corner or rise, meets oncoming car and then drives into the bunch to avoid a crash. If I had my way, the driver would be shot and their car burned.
