However, I'm more concerned with the 'cager computer warriors' who are spewing venom about opening their doors and squeezing cyclists in. So much anger in some people - like a motorcyclist splitting to pass them is a major violation of their right. lol
Personally, I've encountered a situation where someone did open their door a few cars ahead of me. I just took refuge in the empty space in the next lane, waited for the traffic in my lane to pass him and then I continued splitting. I wonder if that ticked him off.
