I still remember in early 1990s London how there was no guarantee a driver would actually stop for a pedestrian even if you had a green man aspect - this only ceased in late 1990s when the signal heads gained IR detectors. Not because they made the traffic light timings that much different, but drivers thought these things were miniature CCTV cameras!
This is also why Sadiq Khan has to go around guarded by plainclothes MetPol officers (some of whom are armed) every time he is out in public in London, the drivers are *still* angry that their "freedom" has been "limited"
