I think the pros outweigh the cons? Anything that steers us away from car culture is desperately needed at this point, and this is one of the only practical alternatives in suburbia.

I would be for bike safety being taught at schools, though I feel licensing for minors would be a quagmire? Let's not go there. I would be for speed limiters that are harder to bypass. For example, I can disable mine by phone app. If I had any trouble I could ask, well, a teenager? lol

But perhaps most importantly, cycling infrastructure, at least in North America, is a joke and there is so much that can be done on the safety front it's not funny. I wish the decision makers were all bike commuters. Then they would understand the level of impracticality in their well-meaning but futile attempts to improve the situation.
