We do about 8000 miles a year in our car.
We both work quite locally so bike/ walk to work most days; although occasionally we drive part way then walk. We try to get the kids to school and nursery by cycling/ walking most days. I took the youngest to today on a child seat and on Tuesday I took the eldest to school on the tagalong.
We try to have a car free day every week; sometimes its 2 or 3 days a week.
I consciously try not to use the car too much, but its not always possible. One thing I find quite sad is people driving kids to school/ nursery when they live less than a mile or two away. We have people on our road for example who are work at home/ stay at home parents and they drive their kids to school.
The other thing that annoys me is virtually all traffic jams are made up of single occupancy vehicles; long-term there needs to be some kind of shift away from this, but I’m not sure how.
Our car costs are this; cost £8k (7 years old now), tax £15 p/m, fuel £55 to 75 p/m + mot/ service (£150 to 250).
