Micro mobility isn't the problem, it's the future of sustainable person transportation. The problem is that we're not updating our infrastructure.
They're on the sidewalk because they'll be killed in the car lanes, and those are the only options. We need better bike (and by extension micro mobility) infrastructure. And not just random lanes that don't go anywhere, we need a whole network. Cars get it, so why shouldn't a safer, more efficient, and more environmentally friendly solution?
