I’m from the UK where in general there’s only a stop sign if it’s needed, such as a junction where you can see absolutely nothing on one side. Otherwise usually there’s a give way line instead, to let people slow the car right down to look, but not need to stop if it’s unnecessary.
Whenever I see a video of an American street, it seems like there’s a stop sign everywhere I’d expect there to be a give way line. Surely this is inefficient as stopping and starting increases emissions, and stops the flow of traffic.
Is it really just the American government doesn’t expect drivers to look properly? Is it so the police can give people tickets for not quite stopping but still doing the junction completely safely?
One explanation could be that many American cities are designed in a grid shape, making many 4 way crossings of equally important roads.
European roads are more often like a tree structure with one road being the main one and with more 3 way intersections, and where the smaller roads have to yield.
Obviously both continents have both types, but due to the city design, USA has many more 4 way crossings.
