come on elon. just use the lidar.

Even a good ol' front facing radar would solve this.

My L2 Hyundai does highway auto-cruise without issue.

You would think so, but early models of the Model 3 have a radar and still do it.

Elon pissed off the company with good radar + camera integration: Mobileye.

In 2016, Mobileye got into a bit of a spat with Tesla, and Mobileye fired Tesla as a customer. Every other company continues to work with Mobileye's radar+optical+ultrasonic solution, but Tesla had to build its design from scratch independently.

Its no surprise to me that Mobileye, with a base of dozens-of-millions of cars, manages to do something better than Tesla (who has less than a million cars IIRC).

Considering they sold 930k cars in 2021 alone, I would guess they have a good bit more of cars on the road now, but less than Mobileye. Radar, as we know from some Autopilot incidents, has problems detecting stationary obstacles.

I sincerely hope all the progress with the FSD package, which is different from the Autopilot software causing the phantom braking, quickly leads to an Autopilot update which avoids phantom braking and is good at avoiding any obstacles.

same difference. he's been adamant about just using vision and it doesn't seem to be working out.

Which car manufacturer uses LIDAR in production vehicles? What they usually do is use radar. As Tesla did in the past. This is less likely to do phantom braking, but on the other side is bad at detecting stationary obstacles (remember all the complaints about Autopilot hitting stopped cars?)

> Which car manufacturer uses LIDAR in production vehicles?

Cars from Lucid, NIO, Mercedes, Volvo, Polestar, Lexus. For example:

While it is true just some chinese EV manufactures use LIDAR right now (Nio, Xpeng), Volvo[1] and Mercedes[2] are on board. I believe once the sensors become cheap enough, people will just use that rather than bet on cameras.

That is true, but currently most manufacturers use a system like the initial Autopilot, the Mobileye solution with radar and some camera information.

LIDAR should be quite for collision avoidance in conditions where it can be used. This should improve car safety quite a bit.

LIDAR can be defeated by a reflected sun glare.

I think the point is not to rely on a single device, but to use an ensemble of sensors that work together to remove single points of failure (single point of confusion?).

And rain
