If your son or daughter had a car that got 30mpg, which is common among today's compact cars, his cost for gasoline to commute would be around $1.75 a week.
If your child's electric car achieved 90 mpg, his cost for gasoline would be $0.58 a week, representing saving $60.66 for the year. Assuming four years of college, his savings on the commuting cost would total $242.64.
Does your son/daughter date?
The car needs to warm to burn moisture out of the exhaust that will build up on a short commute, it will rust out.
The engine needs to burn out carbon which can basicly turn into cement without a greater time running.
I could go on but car guys (and gal's) know the technical aspects.
Bottom line, she's very happy which makes me happy as well. ;-D
