If you have the beta loaded, isn’t radar completely disabled? That’s what I took the email to mean which says that my car is now on Tesla Vision.Good points.
The annoying thing to me is that it wouldn't have taken a rocket scientist to figure out that the current camera suite was inadequate. Anyone who pays attention to driving and thinking like a computer would have realized that you needed better 90 degree side view cameras. Several of them.
The car is only as good as its sensors allow it to be. To take a simple example, auto park. It works, but always parks at least 6 inches away from the curb. A human can do better. Why? Because the car vision resolution at curb level sucks. 960 x 480 pixel resolution by 6 bits of color is horrible. The hardware can't support higher resolutions when driving at 80 MPH, but it sure can use it when driving at 1 MPH. Tesla really didn't think through its camera suite properly.
When I wrote my AI day summary I noted that there was a lot of optimization that Tesla could do that they just haven't had the time to do yet. I wouldn't be surprised by a 2x or more speedup once they give themselves the time to optimize a few things. That's just another reason why I call this alpha level software.
So, I've had a refreshed Model X on order since February but when my turn comes up, I'm now going to defer until I see a new sensor suite. The fact that non-radar AP folks are less than impressed with freeway autopilot also freaks me out (I have radar in my 2019 Model X). Freeway AP works flawlessly for me, and it sounds like they've gone backwards on that.
