I do (or well did) 18k a year and am looking at petrol rather than diesel. Assuming I go back to the office a couple of days a week, 10 miles each way at 30/50 mph wouldn't be any good for a diesel and neither would be my 2 mile round trip to Waitrose (well Aldi....). Even with reduced commuting, I'll still be doing 14-15k a year. Concerned that over time, I'll get banned from some city centres - though remains to be seen if councils have the power to do that as goes against government guidelines.
