A car parked on the street doesn't inconvenience me but a bike/scooter on the sidewalk does - every single day. I'm a cyclist myself. I do like the convenience of dockless bikes for drop offs.
Parked cars are always in the way, the ones double parked blocking the official bike lane are hugely disruptive and dangerous and the nearly permanently parked cars along the side block what could be actually effective biking and pedestrian infrastructure. Just because cars are parked on the "street" and this is the status quo doesn't mean its no longer an inconvenience.
Cars parked on the street are a huge inconvenience. They've just managed to formalize that inconvenience, and we forget about the fact that cars stole 85% of the street while people using their own feet are stuck sharing the other 15% with trash cans, telephone poles, and basically anything else in our public sphere.
