Difficult issue. Overall I agree with you. I happily shared bike lanes in San Francisco w/ various e-bikes — empowering and likely often car substitutes. But there's a huge spectrum of e-bikes, including fast, big machines a hair shy of a regular motorcycle. This one is about 60% of the way there.

Can this Mass. startup solve the riddle of fusion power?
Fusion power's big advantages would be that it’s a virtually limitless source of electricity that doesn’t add carbon to the atmosphere, and has lower safety risks compared to traditional nuclear react...
