The poll does not go up high enough.
Once done 42k in a year and half .uses to do about 420 miles a week just to work and back. Now I don’t have a car just my partner. I use it very little maybe once a month if that or I have to take her to work or something.
So I would say about 200 a year.
Good lord, I hope they're paying you well - you probably spend as much time commuting as Mrs D does at work!
