I guess the question there is whether it's better to pander to their prejudices and spend an eyewatering amount of money on a railway for them in the hopes that they will deign to use it, even though that money could be transformational elsewhere. You could just force their hands by introducing road pricing and low speed limits until they give up.
I keep hearing that this 'money could be transformational elsewhere', but I don't know where else it could be used.
It's coming out of the transport budget for Scotland, so can only be spent on transport, and the only way I can really see a transport project being 'transformational' would be rail connections to a town that never had one (or maybe a dual carriageway built somewhere, but that's a whole other can of worms). Looking at the top 50 largest towns/cities in Scotland, there are only a few without direct rail connections:
- Peterhead (19,060 pop + fairly high tourist demand): Really needs a rail connection, but due to the distance to any nearby railway this would cost an order of magnitude more than this project, and so isn't really something that this money could be used on.
- St Andrews (18,410 pop + high tourist demand + large uni)
- Penicuik (16,150 pop): Most traffic would be commuters trying to get into central Edinburgh, and without bulldozing half of the city, any rail connection would take such a long route that busses would just be faster
