Visited a friend yesterday. For at least 20 minutes of the journey I was driving in areas with 20mph signs and the occasional flashing 20mph 'slow down' sign (activated by other drivers not me)
3 times I got overtaken by people who went passed very quickly with engine noises suggesting they were accelerating hard.
1 time I heard a horn beep. I wondered if it was for me so double checked the next sign said 20 not 30 incase I'd missed it. It said 20. Then a minute or two later there was more beeping behind me and he was gesturing for me to speed up. I pointed at the 20mph sign we were passing and he decided to overtake me at speed just before a sign which flashed up 20mph.
I had set my cruise control to 21mph as when I passed a 'record your speed' flashing sign that speed flashed as 20mph.
Literally no one else was doing 20 but I'm unfamiliar with the area, wasn't in a hurry and definitely don't want points. Also, if it says 20mph that's the speed limit and I kept over to the side in case people did want to overtake. I don't think it's fair to use your horn to speed someone up who's doing the speed limit but AIBU?
FWIW 20 felt painfully slow. I passed quite a few schools but it's the weekend so obviously not open. I checked to see if it was only 20 when lights flash but I didn't see any time restrictions. Once I got to a 30mph zone I did see a '20mph when school lights flash' so it's obviously a deliberate attempt to slow down traffic all day every day. The problem is is people then set their own speed limit which seemed more like 35/40 which is surely counterintuitive?
