I don't think this is comparable. People driving a two ton vehicle have to be licensed, which means they have a general understanding of the rules they're supposed to follow and a general mentality that they should follow them. More experienced cyclists are similar (not in the license, but mentality). A lot of amateur cyclists don't have this mentality on the bike when they start out.

I'd rather they drive a machine that is fast enough to keep up fully with traffic, outfitted with proper safety mechanisms like ABS and turn signals, and wear protective DOT-approved safety gear.

Motorcycles are not that much more expensive but they're much safer. The only reason that ebiking isn't killing people is because it's new and rare, but when that changes it's obviously worse for people to be sitting on the edge of the road at around 30mph with nothing other than a cycling helmet and airpods.
