I hope we come to view this as a lack of empathy.
It's not that at all, look at the road where it's happening... It's fucking 22 god damn meters(72 feet) wide from kerb to kerb, and the speed limit is 35mph(56kph)...
The main issue is the road is very poorly designed.
It seems to me like you're struggling to empathise with people that speed 😂( which if you don't drive is completely fair 😂)
But yeah I agree it's not a good excuse for speeding, just trying to say that putting a sign up is not very effective. It's better than nothing though and a good first step.
But adding speed cameras, while it might help a bit to reduce speeds, it's not very effective, and a much better solution would be removing the root cause of the problem: car centric infrastructure.
Speed cameras don't prevent people from speeding, they just punish people after the fact, whereas better designed roads prevent it from even happening in the first place.
