Care to explain your concerns? I ask not with the intent to attack you, I simply want to know what you think. Since you own two Model S, you've spent a lot of money with Tesla yet you give the impression that you are not enthusiastic about the idea of driving pure electric. I consider that rather unusual: invested a lot of money in two BEVs but "not really sold on the idea of EVs".
Sure, I'm happy to explain. For the Bay Area, and probably Califonia generally, EVs are pretty easy to transition into. My issue is that as I get, er, closer to slowing down my work schedule, I'm heading out in directions that are fairly remote. For example, I have land in Montana that is not only off the grid, it's way over 100 miles from the nearest supercharger. I drive fast in this part of Montana and the range of my P85D suffers at 100+ (not as bad as an X, apparently, but it still drops the range well below 200 miles). The nearest town, about 20 miles from my land, has two gas stations and one main street and no EV infrastructure.
One of my other vehicles is a Ford F150. It has a 36 gallon fuel tank and I can drive it for days without need for refueling. At legal speeds, it has a 600+ mile range, and I am one of those people who can drive for hours without the need for a break (I prefer it that way). At 90 or so, it still gets 400+ miles on a tank.
So for my relatively unique situation, the EV isn't very workable all of the time, whereas an ICE is.
PLUS, I'm a bit of an old school car purist and while I truly appreciate the tech and performance of the P model Teslas, there's something about an ICE with a manual transmission that gives me satisfaction. I have a 9 year old VW Rabbit, a very basic 2.5 5 cylinder with a manual transmission, and even though it's nowhere near as quick/fast as the P85D, it just makes me smile when I rip through the gears, especially when roads get twisty.
EVs are absolutely the future and a good part of me will be happy when we stop burning things to power our vehicles and, instead, use sunshine, wind, nuclear reactions and other sources of energy. But I was raised on ICEs and I have a strong affection for the way they drive. When EV infrastructure is as prevalent as ICE, people will look back on people like me and wonder why we clung to our ICEs. It's just inertia, I think, but I can't deny it. In a generation or so, very few people will have my point of view, and that's probably a good thing.
