Some automatic braking systems recognize pedestrians, and probably recognize cyclists. More of this would be better: Maybe transponders on bikes that activate automatic braking when cars get too close. Sensors on bikes that use loud horns and strobes to warn drives that approach too close. Etc.

New York is an interesting case. While e-bikes are inexpensive and plentiful (and lo-tech, using lead-acid batteries) in China, they are expensive, over-engineered, and rare in the US, except in New York, where I see dozens of e-bikes, most of them inexpensive Chinese-style bikes, on the streets every time I'm in Manhattan. I think this is a sign of people who would not otherwise bike finding bikes are a practical way to get around.
