public transport impracticle
Back when we had the fuel protests, I looked into using public transport to get to work as I do live in a (small) city and worked in a town, both with a train station. My office was 30 miles away and I could do door to door by car in 35 minutes.
However the rail network being what it is where most lines point towards London and not in the direction I needed, I would have to catch 3 trains in both the morning and the evening. A 15 minute walk at the office end and a 25 minute walk at my home end (because the local buses didn't operate so early or so late in the day). It meant my commute would have gone from 35 minutes to over 3 hours!!! (remember my office was only 30 miles away)
About 6.5 hours a day commuting with public transport or a bit over an hour by private car (and probably a lot cheaper still too).
Even now, my current work is a mere 8 miles (about 13 minutes) away by road yet I'd need a bus, 2 trains, another bus and then a bit of a walk just to get to work (and obviously the same on the homeward trip). (Even a bicycle beats public transport on this trip and I might use one if I didn't have to carry tools and a laptop with me and get to work so early)
So, personal car or public transport, guess which wins my vote.
