According to certian statistics it costs me about $0.72 a mile to drive my Jeep Compass. I believe this includes average cost of all possible maintenance, insurance, financing, registration, etc. Basically any sort of cost involved with motor vehicles was factored in and averaged and $0.72 a mile is about what it costs me to drive. I'll be conservative and say would I drive about 7,500 total miles during the time of year I ride bike. That equals a total of about $5400. Since 2008 I have commuted or rand errands on my bike a total of; 1,345.46 miles. 1,345.46 x $0.72 per mile = $968 that I saved by NOT driving my Jeep to commute to/from work or run errands. There is no way I have spent $968 since I started tracking this in 2008 on my bike.
I do not buy that driving a motor vehicle costs the same as commuting by bicycle.
