I cycle and drive.
I don't (well didn't) have a choice as to where I worked as the subject I taught was only available at a college 30 miles away. I didn't move closer as the cost of that would out weight any benefit I got from the job and the job was only on a short annual contract with work elsewhere in between times.
I bought a new car (high depreciation alert!) but after 12 years it has lost, perhaps £700-£800 per year and that figure is reducing the longer I keep it.
I drive to achieve near 70mpg on average. My fuel cost to get to York and back is less then the train ticket for the same journey. The other motoring cost are already paid for regardless of whether I use the car or not for that journey so they don't count.
Often I am seen in the car on my own. What isn't seen, when I was fit for work, is the two tool boxes and other working kit in the back of the car.
Sometimes I drive with a big heavy and empty trailer behind my car. That is because I am either going to collect, or returning from dropping off, something big and heavy.
Sometimes I ride my bike when I could walk. The bike I ride is often considered to be rather over priced for what it is. Frequently I ride for no other purpose then to go from point A back to point A via the scenic route. I get through a lot of cake and Haribo to fuel that. Sometimes the cake is very over priced compared to a chocolate biscuit, which is subject to VAT. When it is cold on a ride I like a hot pie or pasty instead of cake, they are now subject to VAT if I understood the budget correctly.
Stereotyping others and criticising them when their assumed lives don't fit your own ideal is a poor argument.
