Phoenix, where I live, is the red light running capitol of the USA. Since the pandemic started there has also developed a certain sense of 'the rules don't apply to me'.I hope more and more places allow lane splitting. Canada is behind in that respect.
I have seen people fully stopped at a red light decide that they do not wish to wait any more. And so they go - on a a red light. This is not 2 in the morning at a deserted corner, it's 2 in the afternoon with traffic. People are blowing reds after the light has been red for a couple of seconds and I've seen people just decide to ignore the red entirely and just blow through the intersection. Again, broad daylight with traffic.
So I agree with the concept of lane filtering and lane splitting as long as riders and auto drivers respect that. I just do not see that happening based on current experience.
About a decade ago there were a large bunch of motorcycle riders sitting at a red light waiting to make a left turn. A rock truck driver high on drugs didn't stop for the red light and ended up just running over everyone in the left turn lane. He only stopped because the amount of motorcycles and bodies underneath his truck prevented his forward momentum.
You really have to watch yourself out here and motorcycle riders even more so.
