That's my impression too. You'd need to be 80 years old to be excited by a toyota.

Says someone who seems to have absolutely no idea about 'car culture' and no realisation about just how un-cool Tesla's have become. I associate them with their wanker of a CEO, Uber drivers, and parents complaining about being stung on EV depreciation.

My friends who already owned Teslas are doubling down on it (upgrading).

Others are buying cars from actual fascist regimes (BYD).

If that doesn’t raise alarm bells to you, you might be suffering from EDS.

In terms of plain wattage, it cannot be dangerous. Unless, of course, you were to stand with your eye up against the sensor and maybe stare at it for a few minutes.

Lidars use pulsed lasers with peak powers up to the kW range.

Yes but failure cases are still possible. A stuck mirror or frozen phased array can result in a continuous beam.

Engineers should design in a way where the worst case possible is the assumption not the exception

Depends on the type of LIDAR. LIDAR rated for vehicle use is at a wavelength opaque to the eyes so it hits the surface and fluid of your eye and reflects back rather than going through to your cones and rods. It isn't however opaque for optical glass (since the LIDAR has to shine through optical glass in the first place) so it hits your camera lens, goes straight through, and slams the sensor.

You seem to be implying that all automotive lidar are 1550 nm but that's not true. While there are lots of 1550 nm automotive lidars (Luminar on Volvo, Seyond on NIO) there are also plenty of 850 nm to 940 nm lidars are used in cars (Hesai, Robosense, etc). Those can pass through water and get focused to your retina, but they are also a lot lower power so they do not damage cameras.

NGL I thought sub 1550nm LIDAR had been banned for use in new automotive applications already? I clearly must be mistaken but I had thought that was the case.

To date I can't think of any existing lasers which you are intended to look at during daily use. Most consumer facing lasers are either class 1 but hidden (CD-ROM), or class 2 but basically not shined into your eye (barcode reader). There was another discussion a week back https://news.ycombinator.com/item?id=46126780 The lack of accessible certification/testing docs for the lidars is also worrying. Where is the proo…

> class 2 but basically not shined into your eye (barcode reader) TIL barcode readers can cause serious eye damage when misused. You'd think they'd have warning labels on these things given how common self-checkout is nowadays and how curious/stupid children can be

They're not always class 2, some are class 1. I'd maybe suspect the self-checkout ones are class 1 since the object is pressed right against it, while handheld barcode scanners are class 2.

Oh please ... I guess we're going to ignore Gigafactory Shanghai and the parts Tesla sources from China.

Enjoy your fascist Uber, son.

You probably don't want a long range EV then?

Less mass will yield longer range. I know you're referring to the battery accounting for a large percentage of the weight, but a smaller vehicle will get the same range with a smaller battery, and the weight savings compound. If the vehicle weighs less, then all the components supporting that weight can weigh less as well. Unsprung mass can be reduced significantly. Acceleration, braking, handling, and top speed all…

Interesting, yeah, my instinct is that the sensor weight delta would be negligible but perhaps not.

CarPlay and affordability. I was totally smitten last year with the R1S during a test drive. I'm not a car person but felt that spark people must feel when they obsess over their vehicles. But it wasn't pushing-six-figures smitten, which is where you're at when you get a new one with customizations.

>afforadbility This 1000%. Electric cars are supposed to be simple. Give me something in a shape of a Civic, with the engine replaced with a motor and a battery good for 150 miles, and sell it for $10-12k new. Don't even need an entertainment cluster, give me a place to put a tablet or a phone and just have a bluetooth speaker. Instead, we are getting these boutique, expensive vehicles packed full of tech, but in the…

> still fundamentally suck as cars compared to gas alternatives

i can assure you my expensive EV does not suck as a car compared to gas alternatives, its better in almost every way. insane performance compared to any gas car, superb handling, way better driving UX tech, silent, clean. & 400mil range is just fine for me thanks. Yes it cost a lot.

> I hope to god this never ever happens. Then I'll never buy an autonomous vehicle. I get that most people just want short trips around a major city, but given we, I'm sure it's shocking, don't all live in places like that, or want to spend our time in places like that, it might behoove y'all to solve for other use cases if you want widespread adoption (or at least accept that it's ok to solve for those use cases ).…

"we" here is a minority of the population in any developed country. The vast majority of people - almost globally - live in dense areas.

Rubbish.

Population density varies, and your cutoff between "dense" and "not dense" must be tautological.

Autonomy subscriptions are how things are going to go, I called this a long time ago. It makes too much sense in terms of continuous development and operations/support to not have a subscription -- and subscriptions will likely double as insurance at some point in the future (once the car is driving itself 100% of the time, and liability is always with the self driving stack anyway). Of course, people won't like this…

> the alternative would be a corporation constantly providing -- for free -- updates and even support if your car gets into an accident or stuck. That's one alternative. Another alternative would be that you get what you get at purchase time, and you have to buy a new car to get the newest update. "Continuous development" isn't always a selling point when it's something with your life in its hands. A great example is…

I'm getting up there in age and I'm getting a bit tired of designers moving things around.

It's taking longer to update my muscle memory each time.

I still get pissed off at the Play Store app regularly for moving the search bar AND not focusing keyboard input on it when I click the search icon.

I doubt autonomous car makers will offer this themselves. They'll either partner with existing insurers or try to build a separate insurance provider of their own which does this. My guess, if this actually plays out, is that existing insurers will create a special autonomy product that will modify rates to reflect differences in risk from standard driving, and autonomy subscriptions will offer those in a bundle.

Bundling a real product with a financial institution is a time tested strategy. Airlines with their credit cards are basically banks that happen to fly planes. Starbucks' mobile app is a bank that happens to sell coffee. Auto companies have long had financing arms; if anything, providing insurance on top of a lease is the natural extension of that.

Auto companies, yes. As I understand it, airline credit cards are mostly just co-branded cards with existing banks like Chase.
