This would relegate your maximum speed to <5mph or so. That's less practical than just encouraging pedestrians not to be in the habit of darting out from between parked cars right into a lane of traffic.
No, 10 is fine, so long as you're paying attention.
> less practical than just encouraging pedestrians
By pedestrians, you actually mean "people". And it's all people. Little kids, people with mental disabilities, etc. What kind of "encouragement" is really going to keep everyone off the 50% of city land that we've turned into roads? Oh, except for the times you're allowed to be in the street. I've yet to meet an adult who even knows what an unmarked crosswalk is, but we're supposed to make sure every toddler knows this stuff or they die?
Having actually had someone dart out in front of me from between two parked cars when I was going about that speed, I don't really agree. Sure, I didn't hit them, but it was close and very dependent on reaction times for all involved.
> 50% of city land
It's more typically 30-35%
> Little kids, people with mental disabilities
Both hopefully supervised. It ain't just cars that will put defenseless people in peril.
I get that you have a very strong ideological opposition to cars, but let's be practical. They aren't going away. Arguably the utility offered by personal transportation in the last century has driven a huge amount of growth. So short of going backwards, we continue to find ways to live with them. Elimination is a pipe dream of a few super privileged people.
