As a person who is primarily a cyclist, I have a lot of feels about cars vs. bikes and I can definitely say, there are a bunch of dickheads on bikes that are always gonna go through red lights - but it;'s a small percentage. Same with weaving through cars, and being a general dick on the roads. Small percentage.
But groups that advocate for cyclists needing registration and insurance are often just angry at this small percentage of cyclists that don’t give a shit about anyone else on the road. Most cyclists are really good, and I’m glad Toronto has been adding a shitload more bike lanes.
And apart from the obvious argument of car = armored, bike = unarmored, there are wide implications to enforcing licenses and registration on cyclists. You can argue things like environmental impacts, carbon emissions and that bicycles don’t wreck the roads anywhere what cars do, but I think the bigger argument is doing so would completely limit access to travel for already marginalized people; low income, migrants, differently abled, etc.
I always try to remind both sides (drivers and cyclists) that anyone on the road is traffic, and that means following rules. Running red lights isn’t just jeopardising your own safety as a cyclist (and vice versa), it’s endangering everyone else around you.
