I lost my licence on medical grounds in 2004. There was no good reason for it so I was furious, but by the time I had got my licence back five months later, I had become so used to making do without the car that I never put it back on the road. It was only going to Tesco once a week.
I've been cycling everywhere I needed to go, but my health has put paid to that recently, so I miss the car more now. Public transport is a PITA and more expensive. The hospital I use is 20 miles from here, it takes 2h 12m, out of which 68 mins is spent on the train, and 39 mins standing on platforms, and 25 mins walking. (On three out of four journeys I have had trains cancelled, adding up to an hour to the time.) I used to be able to cycle 20 miles in that time, but if I could still do it I wouldn't need the hospital.
Holidays are difficult, too, finding somewhere to go with a Youth Hostel, a railway station, and something to do that's accessible by bus is not easy or cheap. Last summer I had eight days in York for £353, out of which £151 was transport. That compares with £631 for a months cycle touring.
The car spent nearly a decade rusting away in the drive before I scrapped it in 2013.
