I drive around London and even with the one way systems and random road closures I don't get lost very often.
Unlike the small town I drove around earlier. My benchmark tricky road system is Boston, MA, where I have got onto ramps and then been whisked to completely different parts of the city.
I have just had a similar experience in a much smaller UK town. I just wanted to get some fuel before heading back south. I could see the filling station across the seven exit roundabout. I drove towards it, but there wasn't an accessible entrance. I had to keep going.
No problem, I can turn at the next roundabout. But no, they'd built a cunning one way section to stop me.
The filling station was on the edge of a car park. There was a sign to go into the car park. I followed it.
Wrong.
It took me up a concrete ramp into an adjacent multi story car park. The concrete side walls prevent me from turning around. I had to take a ticket at the barrier and drive around the car park and then exit again back into another one way system. I idly looked for another filling station.
No, I would have to follow the road system around to the other side of the filling station which I could now see was across a different car park.
A few minutes later I could see the entrance to the car park.
Another barrier, another car park ticket.
I drove across the car park towards the filling station.
Exit the car park. A big 'No Entry' sign to the filling station.
I decided they did not want to sell me any fuel.
