Hmm. My designed-in-1995 EV1 has a pretty accurate battery gage that is specifically tailored to take into accout the loss of capacity. The new Rav4 has an even better one. If EVs didn't have this down pretty well, you'd see a lot more of us stuck on the side of the road! I wonder what is new about this particular deal, or if it is pretty much the same thing coming to mass market?
