It is a waste of time, I'm just trying to show that ways are treated
differently depending on the type of way, which doesn't reflect
reality and we should be mapping reality.

My point is, just because you can't u-turn doesn't mean it should be
dual carriage way

I did, one side of the centre line is solid, the other is broken, you
cannot cross from the solid side, you can from the broken side.

But it isn't dual carriage way, and it makes no sense to map it as
such, it would be nice to be able to map the lanes correctly however.

Being able to tag lanes along a way maybe?
