^^^ What JG and David said. Tesla doesn't do press fleet stuff, which is annoying.
I did, however, get to drive a Model S P90D a few years ago. It was a coworker's car. My thoughts:
-It felt like driving some sort of experimental test vehicle. Fit and finish was ok, but felt "off" compared to most OEM's, especially the typical luxury marques. To put it this way: it didn't feel like a auto manufacturer made the car.
-It was more cramped than I thought it would be for a "midsized" sedan. That said, it was easy enough to get comfortable once you are in there.
-The tech is everything with these cars, and it's completely insane. The giant center screen dominates your view, but the S has a regular gauge cluster as well. I didn't like the touch controls, but I don't like those in any car, so YMMV. The center stack gives all sorts of info, stats, and more, which is cool.
-It drives like a heavy full-sized sports sedan in a midsize wrapper. Steering feel is heavy and tight, and it handles pretty well. The silence while driving is very odd. This one was AWD, so it gripped as you would expect. Pedal feel is odd compared to a gas vehicle and takes some getting used to.
-I've driven some fast cars in my day, but the Tesla is still the fastest I've driven acceleration-wise. When you mash the pedal, it melts your brain! You feel weightless and you just have to hang on while it nearly instantly gets you to 60mph or more. It's full torque instantly, and so, so awesome. By far my favorite part of the driving experience.
-Autopilot is freaky and strange, but cool. We let the car drive us around for a bit on some back roads. It took corners, regulated speed, and stopped when it needed to. It was so odd, yet cool to see from a technological standpoint. The coworker said he would set it on the highway, read the news on the center screen, and have breakfast while the car would chauffeur him to the exit on the highway for our office. It worked better than the system I sampled on a newer Mercedes earlier this year.
My verdict:
They are cool cars, and if the situation is right and you have the money to plunk down for one, it's an interesting option. If your commute is short, and your office/train station has chargers on premises, they might make sense for you. They don't feel like any other car from any other OEM, and not by a longshot. It's a cutting edge, sporty sedan that will get up and go like nothing else you've driven, and the tech loaded into them is astounding. That said, they aren't for everyone. I don't see myself ever getting into one for various reasons (my commute, price, etc), but I can see why many people like them.
