Recently drove in Scotland where built up areas generally have 20mph speed limits. I found It made little difference in overall journey time Felt safer, stopping distance much reduced Easier to join the traffic Similar speed as cyclists Felt safer and more relaxed as a pedestrian, easier to cross the road
They’re amazing it’s a shame all forms of electric scooter or electric powered vehicle outside of cars and motorbikes are illegal here.
And yet I see them all over the place
