Sure, but what % of the drivers habitually go faster than the listed speed limit? In the parts of the US I live in, the difference between that number and 100 is imperceptible, especially on the roads with speed limits on the lower end (~25 mph).

IIRC the two road users tended to break the rules in different ways, so it's unsurprising that as a pedestrians you might be more aware of one class than the other.

When I'm in London, I check that the first car is going to stop at the crossing. That's by no means guaranteed.

Once the first car is stopped, the others have no choice. All cyclists reaching the crossing can pass on red if they choose, so the comparison needs to take that into account.

a counter point: when cycling in London you have to be aware that 30% of the time there will be be a vehicle stopped the protected bike zone in front of the lights...
