OP is suggesting that it's more efficient to change our whole road infrastructure in order to accommodate a partial solution he likes, instead of having an incremental upgrade that's so compatible with the existing infrastructure that you literally can't tell without looking up the model.
I use electric scooters extensively. I love them. I own an electric MTB. I really really wish all city centers would be for pedestrians and bikes only. But for the love of god, I cannot understand people who pretend that ebikes are a full solution to any transportation issues.
Cars are a solution for somewhere north of 90% of trips in places designed for Americans.
I'm not saying that I love it; as a family of four, we average about 6K miles on one of our cars and 3K on the other per year. I'd be hard pressed to cut that usage in half without significant sacrifice and it would be practically impossible to cut it to 25% or less. Winter skiing alone is probably 2.5K of those miles (10 trips @ 250 miles R/T) and there's not a practical substitute to get from here to there for a weekend of the kids' skiing.
