I can walk faster than 20.
24 is considered speeding.
I live in the bluest of blue states. They use mobile speed cameras in construction zones. They publish that tickets are issued at 12 mph over the limit.
Everyone does ten over.
4? Pikers.
Heck, my 4Runner will go that fast at idle in Drive.
“I can walk faster than 20mph”
No you can not! Top speed of an Olympic sprinter is about 28 mph which is incredible. But a 20mph hour speed limit is just stupid, unless in residential areas with small winding roads of which I did live on in England years ago and quite warranted.
