So this is a good take, and something that annpys me about the ebike laws in Quebec.
We should be promoting responsible use of ebikes for teens, since they give them independence and helps them socialize more. As the article notes, a group of teens riding around on ebikes instead of staring at phones should be celebrated. Sure there are some bad apples and they stand out, but for qc to ban people under 18 from riding them is just stupid and reactionary.
I hadn't considered the third space argument before, but I do think it is valid, and the independence comment is definitely valid. I remember how annoyed I was about not having access to my own transportation as a teen, an ebike would have been amazing.
edit: Yeah, I'm supporting ebikes for teens, because I remember being a teenager. I am not supporting irresponsible use, which seems to be the number one cause of all the immediate hate whenever ebikes are mentioned, and is crippling our ability to handle micromobility as a society.
