Modern sensors combined with computational photography does seem to be changing this though. For example, I now use my phone camera to see where I'm going at night if it's dark, and to read distant text. This is despite my (corrected) eyesight being better than 20/20 and I have better than usual night vision. The eyes are fantastic organs, but the thing that makes them exceptional is the brain. Computers seem to be c…

Flashlight's have come a long way. I much prefer that to using my phone, especially on Android where opening the camera can be finicky and turning on the lamp requires a ridiculous amount of steps compared to the iPhones. Especially handy if out in the cold with gloves. Armytek prime c2 pro is pretty great.

I do love a good torch, and I keep one on me most of the time.

However, I meant non-illuminated phone camera. The new low light sensors combined with AI is incredible. They can see things when it looks pitch black to me.

Also not sure how opening a camera is finicky, just double tap the power button and it opens for me, and turning on the flash takes two taps - though I rarely use the flash.

So... your first sentence is very likely true. But it doesn't match your argument two paragraphs down: > The cheapest bargain-bin cars have this feature. Your $100k+ Model S or X will not. If cheap "bargain-bin" cars have these things, then there is no supply chain problem. In fact it's likely these parts aren't available in quantity anywhere right now and every manufacturer is having to deal with it. It's just not n…

Could you share a source about Ford removing safety sensors on cars that were already ordered?

Ford doesn't sell cars directly. Dealers get what they get, and if this month's new cars don't have Package A then they won't sell that. This happens all the time, just go to any auto manufacturer site and configure the car you want, then call your local dealers to find one. I all but guarantee you you'll find some option package that is supposed to be available but isn't anywhere you can buy it.

And that's my point. No one cares about that, it's just not news. It's "the way the auto industry works". Except for Tesla. Then it's an existential disaster. It's just exhausting.

There are multiple tells that this move, just like the removal of radar, is supply-chain and cost-driven and not actually driven by engineering. If this were a planned move, the software would already be ready to replace it. It is not. Cars without radar still aren't at parity with the car that have it, although they "fixed" this a few weeks back by simply turning off the radar on the older cars. The parking sensors…

Not to be rude, but this is so far off base as to be laughable. You don’t have to understand much about how the system works (really no more than what is contained in the last ai day presentation) to understand why none of this is a problem (specifically the occlusion thing).

It's most likely a hardware availablity issue. They have run out of sensors, and they don't want to pause production until they have produced more.

Seems like the "upstanding" thing to do would be to ship without (and credit for the omission) and offer free retrofit once available.

My understanding is that Ford has done this for non-critical features as of late.

Pardon me for being out of touch, but cars park themselves now? That's pretty neat

Lexus did it in 2006 with the LS460. https://www.youtube.com/watch?v=q9sP-w-xxAI

I feel like Lexus is greatly underappreciated as a technology brand. They might be behind the curve on some things, but when they're ahead of the curve, the execution is always superb.

We've had the complete opposite experience with our BMW->Tesla move. Sure, the BMW had a very nice interior, that complaint gets a tons of play online, and it's not inaccurate. But you know what just blows that away? Getting into a car on a 100 degree day, and instead of scorching my skin on the leather, like I would with our old BMW, the seat is cold because I tapped a button on my phone 5 minutes before when we wer…

>Music that picks up right where you left off when you come back. I have this feature in my 2008 Renault Twingo.

Heh it’s not to say they’re all novel, but they’re all present as standard in the same car.

My 10 year old VW Touran can do it reliably, with only ultrasonic sensors.

Does it drive itself and parallel park?

My 8 year old Golf can't drive itself, but it does a heck of a good job in parallel parking. It works very well, but I have to break and use the throttle.

I agree that Hyundai is killing it, and I will seriously consider the ioniq 6 when it is available. However, I don't think you can discount Tesla here. They produce ~ 5x more model 3's than Hyundai can produce ioniq 5's. And the Tesla battery / motor specs are much better. I don't see any real competition for Tesla at their price point, specs, and production capabilities. Which is frustrating, because I want an EV bu…

Which price point? Lots of non-Tesla EVs selling for a wide range of price points right now. Totally with you on the Ioniq 6 — very attractive, and will have better service options should something go wrong. Would also consider Polestar 2. Maybe the Ford Mustang Mach-E. Maybe.

The only thing matching the Model 3's drivetrain specs (350+ miles, sub 4s 0-60, AWD) is the lucid air, which is more expensive and not in production yet. The mercedes EQS matches the range, but is much slower (and more expensive). Everything else has both less range and is slower. The Teslas also have the best MPGe of all the EVs available.

It is hard to deny that Tesla is dominating the EV scene right now. They objectively have the best, most efficient EV platform and the best charging network.

Realistically, my plan is to wait a few years before I buy my EV. I think with supply chains cleared up, battery tech improving, and old auto manufacturers ramping up their EV capacity, the options will be much better in ~5 years. I really hope the Dodge Challenger EV is good.

Interestingly, all those features you mention are also available on BMWs from the last years. Your comparison is not fair if you compare against an old BMW. On the other hand, on all the Teslas I’ve tried I missed basic things like proper traffic sign recognition, proper adaptive headlights, proper automatic windshield wiper activation, safe lane keeping assistant, etc. those were unusable and unreliable on all Model…

Are they all standard features on a BMW, or available as a dozen optional, rapaciously expensive add-ons? Or a subscription like the seat heaters? ;-)

I’ve heard a lot of complaints about the automatic wipers, but mine have always worked well, better than they did on my BMW. Maybe one of the software fixes in the past couple of years did it?

Unsure about the headlights, they seem to switch on at the appropriate times, but I’ve turned off auto-highbeams.

Autopilot’s been quite good for us, but we have a radar equipped model, can’t speak to vision-only, though my cousin has complained of phantom braking with their vision-only. The speeds listed have always been accurate, but perhaps you’re referring to a different use of sign recognition?

And it buzzes appropriately when it thinks I’m drifting out of the lane without a blinker.

So I guess I’ve just had a very different experience than you for whatever reason. It’s not perfect by any means, but it’s the best I’ve seen, and I’d buy another if I needed a new car.
