in the US, you’ll often see two gas stations across the street from the other. this can seem odd, or even like a design flaw, but the reason for this is to better accommodate drivers, without requiring people to turn around or drive through traffic to reach a station. there’s a reason for it! and that reason is poor street design
to put it another way: in america, it’s easier to build a second gas station 50 feet away from the first, than it is to turn around in a lane
