Filled it in, but a few thoughts spring to mind...
If a load of transport planners fill it in from the link on here does it skew the results?
There's no questions that establish whether or not I do use "alternatives" and if so how often relative to the car. It might have been interesting to ask a question on annual mileage as well.
Quite often I'm required by my job to be out and about in the car, because of that I drive to work when otherwise I could quite happily cycle or get the bus. Other things might cause me to use the car e.g. bus not running late at night.
