No mention of Radar on Tesla Website

I assume miniscule but does anyone know the power savings of not running radar? I assume if a future fsd version doesn't use radar they can turn it off permanently in firmware.

Seems like there definitely could be some power saving from not having to run radar. And I guess there could be some power saved in computing, since Pure Vision will (in theory) be less complex without having to overlay the radar data with the visual data. But I agree it would be pretty small.

There's a theory that the recent delivery delays on the M3s are due to a last-minute firmware update(s) needed, related to the new pure vision system.

Interesting update. As part of the removal of radar from the Tesla website, they also changed the list of standard safety features. The removed Automatic Emergency Braking (AEB) and Forward Collision Warning (FCW). Wonder how related to not using radar this is, and what they will be doing for existing cars.

They also added the interesting language "The following standard safety features will continue to be active on all new cars" that sure makes it sound like the removal of radar also removes some other features.

Before:
Automatic Emergency Braking
Side Collision Warning
Front Collision Warning
Auto High Beams


After:
Side Collision Warning
Obstacle Aware Acceleration
Blind Spot Monitoring
Lane Departure Avoidance
Emergency Lane Departure Avoidance
I highly doubt AEB is gone as standard, must be just an oversight.

Now worried there will be a lot of false positives ending up in false braking maneuvers in city streets.
It is now all uniform data - camera feeds without radar - so it should be actually smoother and less prone to false braking as there I no need to reconcile 2 disparate sets of data into one cohesive representation.

They have to be sure that it will be more profitable.

Never get excited before Tesla delivers. Wait for the product.

Supposedly the x.4.15.x firmwares have vision-based FCW/AEB; my car is on the latest firmware in that chain and I feel like I'm seeing more false positives with FCW (and mine's set to late warning IIRC). Sometimes it's not even clear what triggered it.

FYI:
Automatic Emergency Braking - AEB is back on the site: Autopilot

These camera based adaptive cruise systems have been around for quite a while on other cars as I understand they are cheaper. For example, I had a Mini a few years back on which I had issues with the Adaptive Cruise Control. It deactivated in bad weather and when driving into a sunset (amongst other things). It couldn't be set above 75mph too. I suspected it had a faulty radar but after some research learnt it had "Camera Based ACC" and in the manual it mentioned the system was affected by bad weather, sun and other conditions.

I'd hope Tesla have improved on that system but the ongoing poor performance of the auto wipers since they switched to cameras for that doesn't inspire confidence!
