if you're in Midlothian you can travel to the bottom of Fort Kinnaird through Whitehill Road but if you go further than B&Q, you're breaking the law. These rules do not make sense at all.
Edinburgh and the Lothians should all be in the same tier.
Considering a lot of buses start from Midlothian and East Lothian which go into the city of Edinburgh. I wonder how Police Scotland will handle people travelling on buses from let's say, Tranent to Murrayfield.
