Curious where you live? The only place I ever paid insurance premiums that high (and not quite that high) was in Ontario. I pay $70.

I always chuckle when discussions start comparing insurance premiums without defining the insurance itself. Might as well compare the prices of apples and oranges and vacuums and space stations. These comments could be quoting liability only insurance or comprehensive/collision for a kia or comprehensive/collision with bodily injury for a rivian R1S. The insured amount would differ by hundreds of thousands of dollars…

Why wouldn’t your eye lens focus LIDAR photons from the same source onto a small region of your retina in the same way that a phone camera lens focuses same-origin photos to a few pixels? Sorry if this is a silly question, I honestly don’t have the greatest understanding of EM.

Depends on the wavelength of lidar. Near IR lidars (850 nm to 940 nm, like Ouster, Waymo, Hesai) will be focused to your retina whereas 1550 nm lidars (like Luminar, Seyond) will not be focused and have trouble penetrating water, but they are a lot more powerful so they instead heat up your cornea. To quote my other comment [1]: > If you have many lidars around, the beams from each 905 nm lidar will be focused to a d…

> 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. Doubt that is a politically tenable model. "You're telling me my son Bobby died in a crash that could have been prevented with finished software but they only roll it out to people who have the money for a new car despite no technical limitation?" -- yeah, good luck

I mean that's basically how every car with half-assed barely-functional auto lane keeping sold in the last 7 years has worked.

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…

Uber charges like $100 per hour the customers. I feel once we reach autonomy this will be the baseline.
