I haven't noticed the car thing you say in my neck of the woods. Always have been carholes, always will be carholes. I keep a tally of offending cars for the commuting season. Back to pre-pandemic levels, but not up.
As for e-bikes, yes, the American e-bike sucks. You essentially have 2 different speeds of bikes using a tiny infrastructure of bike lanes. Can't be safe. If an e-bike can exceed 15mph, kick them to the auto lane. There was a pretty good article on this on either Outdoor or NYT, I don't recall which.
