Fife is like Edinburgh, there are good bits and bad bits.
I work in central Edinburgh and commute in by train. The commute is horrific. Trains are unreliable (often cancelled), late, expensive and filthy. Fife Circle line is infamous.
Using car you will get stuck in long traffic queues and there is no/very little parking in actual town centre. What there is is very expensive.
Buses get stuck in same traffic but are cheaper.
Anything, commute wise, goes to hell in a hand basket during the festival and bad weather.
If you can travel outside of traditional rush hour, car is fine except for parking.
Where I live I get to live in a nice house in amazing countryside, but I am currently job hunting on the non-Edinburgh side of the bridge. Four years of ScotRail has made the decision easy to make. 🤦🏽♀️
I was born in Edinburgh but wouldn't move back to live in something pocky or a flat compared to where we are now.
