We need better street design
I don't drive much, but I find that speed limits, or speed bumps do little to reduce speeds. When I was talking to a colleague at work, she mentioned something interesting - speed bumps may encourage motorists to speed up even more once they cross the bump (because they were forced to slow down before). We know that speed limits do little to reduce speeds when the roads are so wide and straight.
I came across this article which I am sure City planners must already be aware of - https://nacto.org/publication/urban-street-design-guide/design-controls/design-speed/speed-reduction-mechanisms/. I think having chicanes would be an excellent way to slow down vehicles by alternating curb extensions/street parking/bike parking on streets.
