I think the humans in London at least do not adjust their behaviour for the perceived risk!
From experience they will adjust their behaviour to reduce their total travel time as much as possible (i.e. speed to "make up" for lost time waiting etc) and/or "win" against other drivers.
I guess it is a cultural thing. But I cannot agree that making it harder to see people in the road is going to make anything safer. Even a robot fucking taxi with lidar and instant reaction times hit a kid because they were obscured by something.

Sure they do, all humans do. Nobody wants to get hurt and nobody wants to hurt anyone else.
(Yes there are few exceptions, people with mental disorders that I'm not qualified to diagnose; but vast majority of normal humans don't.)
Humans are extremely good at moderating behavior to perceived risk, thank evolution for that.
(This is what self-driving cars lack; machines have no fear of preservation)
The key part is perceived though. This is why building the road to match the level of true risk works so well. No need for artificial speed limits or policing, if people perceive the risk is what it truly is, people adjust instictively.
This is why it is terrible to build wide 4 lane avenues right next to schools for example.

The evidence is that they do though. E.g. the Exhibition Road remodelling (removing curbs/signs/etc.) has been a great success and effectively reduced vehicle speeds, e.g. https://www.rbkc.gov.uk/sites/default/files/media/documents/...
There are always going to be outlier events. If for every one person who still manages to get hit—at slow, easily-survivable speeds—you prevent five others from being killed, it’s a pretty obvious choice.
