1. Ventilated Seats. I have them. They're loud and annoying. And they definitely don't keep you cold. But they do prevent you from sweating. So I guess they do their job. My wife loves them. It certainly seems like they could have been implemented better, though, and hopefully that's why they're MIA at the moment - going through design improvements.
2. Seat comfort. I think the seats are fairly comfortable, especially in ultra white. I could definitely see something more luxurious being more comfortable, though. I think we need to change our wording though for this whole thread. The X is definitely luxurious. It's just not opulent.
3. Shifter. Huh? I love the simplicity of the shifter in a Tesla. Small, simple, easy to use. It's a simple flick, not like a minivan at all where you have to pull a large awkward stick towards you and then down. Oh, and don't worry about putting it back into part most times. When you press the brake, the car goes into vehicle Hold, and won't move. Then unbuckle and get out - it'll put itself into park automatically (actually any time it doesn't have 2 out of 3 of seat buckled, seat occupied, and door closed, it'll automatically put itself into park. That bit my wife once when she lifted her butt of the seat to look backwards, and hadn't buckled yet). And yes, it's the exact same part as in a Mercedes.
4. No 360º top-down view. In theory it sounds nice. And I'm sure if Tesla were to implement it, it'd be great. My comparison is my Nissan Leaf that has it. And my conclusion is that I far prefer my Model X with 360º ultrasonics that show me exact distances on a giant touchscreen, than the top-down view from average cameras on a tiny touchscreen with terrible contrast. But as stated elsewhere, I think Tesla is focusing more on autonomy than improving these sorts of driving experience.
5. Lack of DVR. Definitely! Especially in AP 2.0 cars with lots more cameras. Just remember that only the rear camera is HD and full color. the AP cameras are more grayscale or something. (Another reason you can't use AP 2.0 cameras to implement a 360º view).
6. Driving comfort. I'm pretty sure this just depends on what you're coming from, and what your expectations are. I love how our X rides, but I don't have much experience with high end suspensions. Honestly I think a lot of the ride comfort comes from the smoothness of accelerating and braking.
1. Free supercharging. Meh. I have free supercharging, and I actually use it (as in more than 400kWh annually -- I'm up to 16k miles in 10 months, with several 1k mile road trips). But it's all psychological. If I could have dropped the price of the car $5,000 and paid-as-I-went, I totally would. Tesla's rates are surprisingly competitive. And really the important thing is the experience - you drive you, plug in, and it charges. No futzing about with a touchscreen to activate it, oh crap nevermind I have to use an app on my phone for this one (yes, I'm serious, this is the DCFC experience in my Leaf), figure out how to pay, etc. Credit card on file associated to your car maintains this experience. Other networks need to simplify too -- just accept NFC payments at competitive rates, and screw all this complicated signing-up-ahead-of-time-for-this-network business.
2. Falcon-wing doors. LOVE them! Very very functional, and besides an initial calibration at the service center due my car being an earlier build, they've worked flawlessly. Even the one that has had a run-in with an F-150 (see the Safety point below). But they are definitely showy. We've just kind of learned to tune out all the stares. And if you live in a more Tesla-dense area, it's probably not as bad. They're definitely not slower or worse than electric minivan doors.
3. Giant Screen. LOVE it. We always keep the read camera up while we're driving (why don't other cars let you do this!?). And the UI is definitely far better than any other car I've been in. And keep in mind the UI is well designed to allow many operations without looking by placing key controls at corners or around edges. There are times that I wish some key features could always be accessible (but understand why they can't, and am totally willing to compromise on them in order to get the other benefits of the simplicity and ease of the touchscreen) is door and interior light controls. My other experiences are with an Audis and Mercedes that I've had rentals of. And they're so damned complicated, even with big LCD displays, that I just end up not listening to anything and if I'm lucky I'll find the temperature controls.
4. Having never experience a HUD, I don't know what I'm missing. On the flip side, the fully digital IC is far better than any other car I've been in. I'm sure a HUD would be a nice evolution of the IC, but again, dunno if Tesla will head that way.
5. Keyfob size. Meh. It seems about the same as other keyfobs. Maybe a little bit bigger. But I never ever ever have to take it out of my pocket, and it does fit in my pocket, so I don't care. I'll definitely admit unlocking and locking isn't immediately apparent. But once you've figure out that double tap opens things, I love that I don't have to look at it in my pocket to open any particular door/frunk/trunk (though I do wish I could individually close things, instead of all at once. Oh, and open the passenger door without opening the driver's door first. But at least I can open it at all now).
6. Spare tire. Meh. Again, colored by my own experience. I've never had a flat in my life. Though about a month after we got our X we got a low tire pressure, and I had to keep topping off one tire for about a month until I actually got it looked at and replaced because it had a nail in it, right at some seam that they couldn't repair it. Talk about bad luck. But as others have said, this is getting more and more common with modern cars.
1. Ludicrous mode. I have a 90D, with 0-60 in 4.8s. I definitely wouldn't accept less from a 75D now! I've had a Model S P85D loaner, and can definitely feel the difference. My X pins you to your seat. A PxxD(L) knocks the wind out of you. Sometimes I find myself wishing I had a bit more in my X, especially when I'm punching it at higher speeds to pass someone. Do you need Ludicrous? Definitely not. Will you enjoy it? Probably. Is it worth the cost? Up to you. It's definitely a very expensive feature for essentially a party trick. Can you part with $30k for something that you'll "need" once a month? I couldn't. When I upgrade my Leaf to a Model 3, I'll be paying very close attention to these performance numbers and prices. It'll be a close call.
2. Safety. You hear lots about this. Besides what Tesla tells you, I feel like they have a long ways to go with active safety features. In particular, why isn't AEB active when you're not in TACC? Blind spot detection (at least in my AP 1.0 car) is definitely subpar compared to similar vintage vehicles. The amazing rear camera that I have on all the time makes up for that somewhat. And I'm hoping AP 2.0 cars are much better in this regard, given better ultrasonics, and hopefully they do/will make use of the rear-face side cameras for this purpose as well. Oh, and AEB with 8.0 is amazing - that it can bounce the radar below the car in front of you so that your car will stop even if they rear-end the car in front of them. This is one of Tesla's best features - not just that it does the radar thing, but that this significant feature was added in a free software update, and my car that had already been built and delivered before the feature was conceived got it. Another aspect of safety is traction control. This last winter, I felt the safest I ever had, regardless of weather and road conditions. The car is heavy, low, and torquey. The reaction time is instant. It's almost impossible to lose traction. It happened only once, for a split second, and a very large smooth sheet of black ice. And final aspect - yes, I got hit. Two left turn lanes, I was in the right lane. The light turned green and the guy next to me tried to go straight... right through me. He was in a large F-150, and my Model X definitely "won". A small dent in the FWD, some scrapes on the rear quarter panel and the wheel. The other guy blew out his tire, nearly ripped his bumper off, and had more damage further down the side. Well... until the repair bill comes through. His insurance will sure know who "lost" then. Anyhow, the moral is I was in a medium speed collision (15-25mph), and I felt completely safe.
3. AutoPilot. Yup. Wish I had AP 2.0 where it can get even better. But I love what I have, and don't regret getting it 6-8 months sooner for an instant.
