The UK has no jaywalking laws (apart from full motorways) and about 1/3 the pedestrian deaths of the US (https://usa.streetsblog.org/2020/10/10/exactly-how-far-u-s-s...). There are other ways to do things.
Cars on a Monday. Lorries and HGVs switch on Wednesday. All remaining traffic on the Friday.
Done!
(Note that it was a follow up to patently satirical parent comment, but it does remind me that Sweden made the change on 3rd Sep 1967)
Edit: why disagree? We should be focusing on education and testing for the best improvement as it will be beneficial to multiple problems.
Kind of https://www.worldatlas.com/r/w1300-q80/upload/58/85/6f/shutt... vs https://mobycon.com/wp-content/uploads/2019/09/IMG_20190725_... - that's not quite a fair comparison but that kind of thing.
Also pedestrian deaths on the highway: the number is so minuscule it doesn't even register.
This is only really true for a very small number of places in the US, even smaller when you consider the lack of enforcement.
And they aren't as dangerous as many would think. Cars have done lots to improve such collisions (airbags, crumple zones). A head-on collision between cars is still two relatively lightweight objects. Hit a concrete wall, overpass support, cliff or tree and you are going up against an object that makes a care look like tinfoil. The head-on seems bad, but it is more survivable than having your car bisected around a tree trunk. Or get pulled under a big truck.
