> They belong in the bike lane (which should exist in the first place)

A bike lane really isn't safe enough to get people on bikes and scooters into it. It needs to be a separated cycle track like what is common in Copenhagen. This takes more space, but increases capacity of the whole road (the cycle track has more capacity than the driving lane it takes away).

There are a zillion other benefits too - more active/healthier population, higher retail spending along the cycle track (https://its.ucdavis.edu/inthenews/the-complete-business-case...), higher property values, only taking 30lbs of metal with you on every trip instead of 2000lbs, potentially local fuel source (food from nearby rather than oil or electricity from afar), etc etc etc.
