Call me crazy but I suspect you and your brother drive a different amount. $100/mo in a Tesla I ballpark at driving 1900 miles per month, so you're probably driving less than him, unless you get more than 150mpg in your hybrid.

He has a 5 mile commute to work. I figure at the most, he drives twice as much as I do, but that would still be less for gas than what he is paying.

All I'm saying is that Tesla claiming you are going to save $100 a month in gas is based on a whole lot of assumptions. It's not money in the bank.

That's pretty good ballpark. His electricity rate matters too, but I'm about $100-120/mo and average just under 2k miles.
