I've done this, got a slight problem with question nine as at no point does it mention cost.
Being a skinflint Yorkshireman, cost is king, I would use any form of public transport as long as it got me where I wanted to go in a reasonable time and was cheaper than my current car usage.
Taking this a step further, If I have a round trip of 36 miles... it costs me the following -
Fuel - £3.50
Tax - Nil
Insurance - £0.80
Servicing/MOT - £1
Street parking - Nil
Total £5.30 Return
Current train price, which involves a two mile walk to the Station. £7.20 return. Limited choice of trains.
Therefore, I am about £430 a year better off in the car... I appreciate I haven't taken depreciation or major breakages into consideration.
