I suppose IF you purchased the car so save money on gas you'd be defeating the purpose. If you purchased it just to have fun the oil producing nations thank you.
Personally I find myself doing the same thing. If I drive 3 miles to work I get 30 mpg on the ECO meter. If I drive 4 miles to work I get 40+ mpg on the ECO. Sort of like getting the 4th mile for free.
