I only have two rules concerning transportation.

I refuse to get on ANYTHING that does not have a hand or foot braking system. That includes animals.
They don't want to ride me, so I pay them back by not sitting on them.

Two? I have to be able to get whatever I am using, home.

I have nursed cars and motorcycles home on wings and prayers.
I think that calling for a tow is above me.

If you are creative you can..

Bump start a manual transmission car, by yourself.
Change a tire in 10 minutes.
Use a piece of wire to replace a fuse
(Not recommended for extended use, just to get off the center median of the freeway.)
Make a funnel out of discarded trash.
Figure out that the idiot light on the dash is a loose gas cap.
Change your sparkplugs/air filter/wipers.
Figure out why the door doesn't close correctly.
Get a motorcycle home with a throttle cable.
Find a short in a wiring system. (Too bad newer cars are all computer BS)
Change a hose, flush a radiator or belt.
Program the radio.
Hang an air freshner.........
