lol, the batteries are only covered for 8 years,regardless of mileage and are only expected to last 10.I have had a solar system for years and also know the range will dwindle quickly enough. I have no expectations regarding mileage cont.

2- and there's really no precedent set to prove the mileage claims you've used

Actually, there is. EV's have been produced in quantity globaly since about 1997, introduced into U.S. markets (hybrids initially) in 2000. 23+ years of data compiled from millions of miles driven and associated cost analysis.

I can only find projections or warranty info related to the mileage life of a battery, not actual numbers. Do you have a source?
