Correct me if I'm wrong, but as far as I'm aware, ODs in London get a similar mileage rate to the rest of us. So how do they earn a wage?
The other day I did a job from South Mimms to Vauxhall Road, 18 miles. I made an acceptable wage from it, but only by charging £40 = £2.22 plm.
I left South Mimms around 6pm and didn't get back to the M25 until 2hrs 45mins later. My engine was running for the whole time apart from 15 mins unloading. If it had been during the day, there'd have been the congestion charge to factor in as well.
I bet I used my clutch and brakes as many times in those few hours than I do driving all the way to Scotland. Has any comparative study been done into the difference in running costs (not just mpg) between city driving and motorway driving? It would be helpful to know a figure to help calculate urban running costs.
