So how much gas is being saved by these short trips? Enough to buy a new battery pack?
Not sure that the car will every pay for itself in gas savings. Most EV's are fairly expensive. It's the bleeding edge self driving tech that many desire for the boring daily drive to work. It's certainly not perfect yet but getting there.
The current battery tech is good for at least 10 years and some of the new stuff will be guaranteed for 1,000,000 miles.
