Cars are a huge impediment to creating walkable downtowns, even if they're green. This is downtown Annapolis, looking down Main Street: https://www.google.com/maps/@38.9777543,-76.489652,3a,75y,10.... On a nice summer day (this picture is in October), the sidewalks are packed with tourists, but a handful of cars take up most of the space. Further down the street, you get to this giant expanse of pavement: https://www.google.com/maps/@38.9773508,-76.487682,3a,75y,67.... To get from the main drag to the water front (in the distance in the picture), you have to cross this expansive waste of space dedicated to cars.

All for what? The whole downtown area is walkable, and there is a perfectly good multi-level garage at the edge of Main Street for people to park in.

> This is a massive reduction of comfort, a burden for families with small children and people with disabilities, as well as businesses and logistics.

Parents don't need to drive up right to wherever they're going; their children could do with a little walk. I've got a four year old, and we go downtown every weekend. It's no problem to park in the garage and walk half a mile to where we're going. At the same time, it's a big worry to have kids running around with traffic zooming by.

Deliveries and disabled people can be accommodated by permitting busses, special vehicles for the disabled, and commercial deliveries during certain windows. You don't need to permit all vehicle traffic to accommodate those special cases.
