I have put out a new patch that does that.

Most people do drive on the right, surely that's good enough!

That's a subtlety that we can't really cope with.

Perhaps you should point that out to those who are proposing these new

Well, the code will still recognise left/right/both as well as
track/lane and they all do the same thing.
