I love my car, and at times it's a necessity. My sons under 13 football league has a radius of about 30 miles. As much as we love cycling a 60 mile round trip plus a match may be a bit cruel!
I also work shifts in a busy kitchen. While I often commute (12 miles each way) in the week, the idea of riding back at 1 in the morning after cooking 160 meals in a 40+ degree kitchen is not appealing! I would get the bus but the last one leaves town at 10.30.
It's also the best way I have found for getting me and whoever else to the alps/Pyrenees for my annual summer jolly where it doubles up as a workshop and hotel.
I think if it weren't for my children I would buy a moped/skooter type thing for rough days and do what all my "I don't need a car" friends do, bother someone with a car occasionally.
