We're not all frigging bankers and stockbrokers, and it's not exactly a cheap place to live
Higher density than Cornwall, but 'high density' ? - I'd be curious as to how it compares to the rest of the uk. There's some big towns and it includes the edge of Greater London, but there's an awful lot of green space in between - ISTR we've got the largest proportion of tree cover in the UK. But relatively wealthy is correct, but with an awful lot of people driving around which probably doesn't help - public transport's decent if you're in the right place but patchy otherwise.
Certainly you'd expect the roads to be in decent nick, but Surrey County Council seem to be a law unto themselves...they've finally got around to patching up the worst holes in some of the roads locally, whilst leaving others which are little better a few foot away and will soon disintegrate in a similar fashion, some of the patches are repairs in previous patches so you can imagine the result.
In any case, crap roads are one thing when there's not much traffic, but when you've got to dodge the holes *and* the drivers...
