When I lived in London, it used to take me an hour and half by public transport to travel 15 miles. When I changed work location, it took me an hour to travel 7 miles by car (no easy public transport to the locality I worked in). That was at 6am. It's the same problem in the whole of the UK. It now takes me 45 minutes to get to work in Cardiff, a distance of 35 miles from where I live.
