Thanks for the thoughts folks. Perhaps car usage is higher in Glasgow/Manchester than Edinburgh. Edinburgh is a nightmare to drive around as the road system is very small with two way overcrowded streets. Still not sure how Lothian manage to operate a dozen hourly service routes, some heading out into the sticks and it is a proper service, as in, operates in both directions, not just clearing punters out of the city centre. Was just genuinely taken aback that bar Glasgow airport to city, nothing was in play. Thing is...why would anyone drop self drive BEFORE an adequate transport system is in play?
