a car changed lane from behind and cut in about only 2 meters in front of me, from my right hand side, taking me by surprise. i was riding at the speed of 70!. it is still too slow for them?? i was pushed to the left almost have to go to the left lane, i saw a red car closely behind on my left! I was furious, there is a red light and this car has to stop, i went up and punch his window and yelled at him, and this men just looked to the front as if he was deaf! i saw many cars change lane on me without even signalling, some do this because i am a tiny L on a slow bike, what can i do, but at least most of them give me enough distance and time to be preared!
