I pay my share of the burden for your bridges, roads, traffic cops, traffic lights, parking spaces, and the public health cost for your parking too. It's no straw man- the burden of automobile traffic on our society for the benefit of a few auto manufacturers is hugely out of proportion. I applaud any dent that any public or private entity can make into alternative modes of transportation. Is it a cash grab? Sure, in some respects. But if it results in a widened bike lane that scooters can share too, or a way for me to bike around the city without getting a car door to the face or worse, bring it on.
Dodging a parked scooter on the sidewalk is no more burdensome to me than having to step around every parking meter that crowds the sidewalk presently.
