That's insanely dangerous. Here in Toronto 3/4 of all collisions between bicycles and cars occur on sidewalks (car pulls out of driveway and gets hit), and just a few days ago a woman was killed when a cyclist ran her down on the sidewalk. The safest thing to do is widen the curb lanes a foot or two (just a matter of moving the lines) so that cars can get around them.

The issue you’d encounter there is people parking in these widened lanes.
I hear what you say about the sidewalks.
Here in NZ the NZ Post delivers letters using small motorbikes (you guessed it) by driving on the sidewalk. It is definitely a discipline to watch out for them as they scoot around, when pulling out of the driveway. Bikes aren’t generally permitted on our sidewalks, but skateboards and mobility scooters are.
When it all boils up, the motorist does need to be careful for the hazards, no easy way around it.
