No driving for the next 6.15 years

I made a two furniture purchases^H^H^H^H^H^H^H^H^H *INVESTMENTS* today. After some estimation afterwards, I realized that I need to make up for the money I spent by not driving to work for the next 6.15 years. Here's how I got this number:

round trip commute to/from work: 20 miles
cost of a gallon of regular gas: $2.7
average miles per galon on a prius: 44.5
Rough estimation on the purchase: $1941.84

$1941.84 / $2.7 * 44.5miles / 20 / 5 / 52 = 6.15 years

Dear reader: if you consider me your friend, please spare me a ride to/from work each day for the next 6.15 years.
