Now we do joke about a lot so he could have just been winding me up, but in the grand scheme of things I am regularly tailgated and/or overtaken in my locality when driving at the speed limit, so is it me that's causing a hazard?
I get the same tailgating if holding to the limit, many drivers really resent the 20 limit in my borough. Overall most drivers run at between 25 and 30 mph now, which is 10 mph slower than they used to, so it has had a major effect. I believe this could have been the intention all along, just reducing speeds rather than any fixed limit, since they've openly said that no-one will be doing any enforcement.
It seems to be a conscience thing, the repeater 20 signs on many lamp posts in every road constantly reminding.
My new car reads the signs and displays them on my dashboard anyway, which has had an amusing effect. At the end of my long 20 limit road where it joins a 30 mph through road there's a 30 sign to show I'm about to enter that and the car dutifully shows me the 30 limit sign on the dashboard.
Trouble is that opposite my exit where I turn left into the main road there's another residential road with 20 signs at its entrance, so the car immediately switches back to 20 on the dashboard. That leaves me showing 20 in a 30 limit road for a minute or so until the GPS information backup corrects it.
Another illustration of how difficult it is to apply intelligence to cars and why true self driving cars are still a very long way off.
