We like to assume that there are many people on the forum who bike. However, there are always a lot of people who say they can't because of the number of major roads, the distance involved... and most of them seem to say that they use a car.
I wondered what the ratios were, and what other methods of commuting there are in the forum. For example, my brother lives in a neighbourhood with very busy roads, and doesn't bike because it would be too dangerous. However, he rollerblades everywhere instead (when their children were little, he wore out the wheels on the pram by because it had done so many kilometres of rollerblading).
The modes of transport are organised as powered (self), powered (mass transport), unpowered.
