Without cars there would be no reason to have signal lights at intersections. Cars are clunky, slow to accelerate, sound dampening and huge, which is why they need all this wasteful infrastructure to make them feasible at all. People on bikes have much better vision and hearing so if you pay attention to the traffic situation, its not necessarily dangerous to run a red light.
That’s why I love my small electric car, all your complaints are invalid for it and I don’t have to freeze or get wet when I need to travel far up a giant hill.

Electric cars are heavier, noise dampened, and have the same blind spots, they do accelerate faster though depending on the situation that can just make an inattentive driver more dangerous.

Electric cars are better environmentally then gas cars but they certainly don’t absolve the need for traffic signals the way purely pedestrian and cycle traffic would

They are better, but only in a few ways. They are still very bad for causing sprawl, they shed microplastics etc.
For the audience, tires are not made of “rubber” these days they are made from modern plastics.
