30 years and counting, I guess I have a lot of luck.
Did you guys really have enough time to safely move to the right lane? watch the video again and tell me. It's easy to say he didn't ride properly and didn't leave enough space but realistically in Toronto if you leave more of a gap than what he did, everyone will be taking up the space in front of you and make it more dangerous with people shoving their cars in that gap. At least to the left he knows cars are not going to crash into him.
Anyways, to each their own, none of us were there.
That is where you said it.
As someone who has also been hit from behind while stopped at a stop sign on my motorcycle by a fool in a car I (possibly) feel the same physical pain as you. The point I am making is that when you leave space you have more options and with the increased number of options comes the greater possibility of making the best choice for yourself. If you leave a proper gap, you have the option of braking, but if you try that an realize that the driver behind is not paying attention and not stopping you have then the option of moving around to other lanes. Motorcycles will not outbrake most other vehicles, but they will certainly out accelerate most.
