2 Seattle doesn't have police to be setting speed traps; it's also racist (I assume, since enforcing fares on transit and stopping cars with outdated vehicle tabs is considered racist here)
> Can drivers used to the higher speed not read the updated signage?
I live near a road that looks like a highway, and is 55 mph through a quieter area between towns. As you approach the business-heavy area, it drops down to 45, 35 mph, but the design is the exact same.
It’s impossible to feel how fast you should be going because the entire road still feels like a highway, so you’ll just naturally go fast. Most people don’t look down at their speedometer very often.
I have to keep looking down and correcting because your speed just naturally creeps up when a road feels like a highway. And this is as someone who lives near there and drives it regularly! Imagine the people who don’t go that way as often and aren’t aware that they should be making adjustments all the time because of the terrible road design.
TLDW: People don't obsessively check their speedometer and thus changing the speed limit largely doesn't affect the speed people drive at. To effectively change that you need to change the road design.
Or car design. Automatic speed limiters in cars would solve this. It's not rocket science tech wise but car lobby is fighting tooth and nail to delay and cripple the implementation (hence delays and softening of the regulation in EU).
