Or increasingly 'savvy' I would say Gordon, the cities who are anxious to jump on the 'Emissions' bandwagon will slowly become to realise the impact on tourism. I myself avoid cities like the plague regardless of country if at all possible but as Scania said it will eventually spread to just about everywhere over time.
My 'second home' in Wales by the coast has not seen me or my MH since August 4th not for emissions but parking charges and bans on overnight parking for MH's so just for me alone that's £2k a year local businesses wont get. Short term gain for Long term pain. And the biggest employer in the town has decided to relocate it business, even more pain!!!
Fewer jobs, fewer visitors and once they have gone it's a major battle to get them back, if ever.
