That's what people at work are doing now.
They know I ride my bike as much as I can, but are seemingly surprised to see me ride on all directions of roads to and from work.
I do this to add miles onto the commute and to stop it getting stale, but they think my 'normal' 2.5 mile commute is 'extreme', so when I say I did a quick 15 miles before work, they think I'm crazy!
I think they're mad paying the taxman 40-50 pounds a week in petrol when they can easily do some of their journeys on a bike?
