That's the crux of it. Most places outside of London don't have good public transport.

I can catch a bus but I have to walk to it, it comes at most twice an hour (usually hourly) and it a very circuitous route so it take ages.

Or I can drive 15 minutes from my door but it's expensive to park. So I generally head in the other direction to an out of soulless town shopping centre.

It would be luxury to have something like the Tube arriving every 2 minutes. I love it when I'm in London.
