With a lot of the decisions Tesla's been making lately, I'm not sure I'm going to buy another either. I'm mainly speaking of:

- The butterfly steering wheel. - The removal of radar for Autopilot (I'd like to have multiple systems for this, not just cameras/vision). - The removal of steering column stalks (and using the sensors to figure out which direction you want to go). - The door open mechanism changing from handles to whatever this button situation is.

I'm sure there will be other stuff, but yeah, may have to cancel my reservation for the Cybertruck.

The talk by Karpathy sheds some light on while they removed the radar. TLDW: Radar is inaccurate and buggy for a few seconds, then typically returns to normal. And the sensor fusion is difficult too. FWIW, I still think they're dangerous. I don't want my car to be "production." Engineers were SSHing into tons of cars to apply updates according to an insider thread a while back.

New firmware update going out restores safety features with vision only. Consumer Reports made the 3 its top pick again due to this.

https://www.consumerreports.org/car-safety/tesla-model-3-reg... (Tesla Model 3 Regains CR Top Pick Status and IIHS Safety Award; New IIHS testing shows that Tesla’s new camera-based system provides effective automatic emergency braking)

> The Tesla Model 3 has regained its status as a Consumer Reports Top Pick after independent tests proved the effectiveness of its new camera-based automatic emergency braking (AEB) and forward collision warning (FCW) systems.

> Earlier today, the Insurance Institute for Highway Safety released the first evaluations of new Tesla vehicles that use a camera-based system for AEB and FCW. Because of their performance, the Model 3 will once again get a Top Safety Pick+ designation, which is the IIHS’ highest safety award.

> “Given the IIHS’ recent evaluations of Tesla’s new camera-based system on its Model 3 and consistent with CR’s integration of IIHS ratings into our recommendations, CR is restoring the car’s Top Pick status,” says Jake Fisher, senior director of CR’s Auto Test Center.

Radar based cruise control, like what my Toyota has, is pretty inaccurate. The shape of a vehicle affects how close the system estimates it to be. Its size too.

Maybe that's just one badly implemented system. But my eyes don't judge a vehicle's distance differently because of its size or shape. Usually :-)

If you have two different systems for judging distance, you still need to decide which one is correct. Maybe if there were three, it would be more reliable.
