....or let them through a gap not wide enough for two (pedestrian and car).
That bit made me think of a real driving hate.
You will know the situation:
Road barely (but obviously) wide enough for 3 cars.
Car coming toward you with one parked on his side.
You're as far over to your left as you can be.
He goes round it, still coming toward you.
Fair enough.....BUT:
He allows enough room for the PARKED car to (fully) open its door!.
It happens so often, strangely most often to me on the widest road in my area.
If you've ever found yourself muttering "get over you ****" you will know precisely what I mean.
They're letting the highway code override common sense. Don't force the oncoming vehicle against the curb - if the parked car door opens, it deserves to be smashed off.
In that circumstance, it's not practical to give it room to open to its
full extent - as so many seem to do.
