They are working on that, well... kind of. They somehow convinced the NYC government to allow them to legally operate little trucks in bike lanes. They claim that they are "bikes" (bikes have two wheels, that's what "bi" means, these have four)
I like those vehicles, honestly -- delivery trucks are going to park in the bike lane regardless and these are much smaller and safer to maneuver around. I want to see more of them and hope it leads to more bike lanes being built in NYC.
Amsterdam lets little vehicles like this operate in its bike lanes. They can't be capable of going over ~30 mph. I imagine a similar policy is being followed here.
Normally I have no problem with "bicycles" having more than two wheels operating in bike lanes (for example: recumbent trikes, trailers), but I agree - those vehicles seem more like golf carts than cargo bikes. I'd be interested to know how much they weigh empty and what proportion of their power comes from the rider rather than the "assist." Probably better for the city overall than a full size truck but I wouldn't be stoked to share the bike lane with one...
Also those are definitely going to be parked blocking the lane lol.
