Phantom braking under overpass has now been replaced with Line of traffic lights as overpass.
So, the radar wasn't the problem all along. It was the vision. And now, that's all we'll have going foward. How is this progress I ask????Just picked u my new 2021 Model Y 4 days ago and drove it 1000 miles home. During that drive I experienced this phantom braking 15-20 times on the highway, several times it was quite hard braking, 75-85 mph down to sometimes 45-50 mph before I could mash the accelerator pedal to correct. Luckily no one was ever close behind me, although I'm sure a few people were wondering wtf I was doing. This is most certainly not fixed yet.
And I also can't use cruise control at night because it commandeers the brightness of the headlights, leaving them on high beams while vehicles on the other side of the divided highway constantly flashing me to turn off my brights.

not enough info to jump to that conclusion.So, the radar wasn't the problem all along. It was the vision. And now, that's all we'll have in the future. How is this progress I ask????

Umm he’s right. 2021 Model 3/Ys without radar are required to use high beam when autopilot is on. Just another frustration for people with vision-only cars."Just picked u my new 2021 Model Y 4 days ago and drove it 1000 miles home.

really? there really are people who don't know the cruise control is NOT coupled to auto high beams? wtf. that is a deal breaker...read the manual. find the setting. LEARN about the vehicle is which you drive. just...kinda funny but seriously...high beams and cruise are tied to each other? that is a new one.
FWIW, my car does not have that feature. cruise and auto high beams can be set separately. '18 Model 3 long range RWD.
wow.
Do you have the link to the actual video? I'd be interested in watching it whole!No. Karpathy mentioned at CVPR yesterday that radar was the problem all along. He even gave a couple examples of how the radar sucked and Tesla's sensor fusion sucked. Tesla solved the problem by removing radar. With Tesla Vision, the phantom braking is gone or greatly reduced and braking in general for objects is much smoother.

oh wow, only 8h! Thankfully it's not a leek spin loop haha
7:50:30 mark is where Karpathy starts (must be watched on YouTube)
The Tesla portion is only ~38 minutes. And is split out in a separate video here:oh wow, only 8h! Thankfully it's not a leek spin loop haha
It is actually connected to TACC/AP in 2021 cars without radar. I just picked up our new one, and it is every bit at bad at night as described."Just picked u my new 2021 Model Y 4 days ago and drove it 1000 miles home.

I completely believe that sensor fusion was a potential roadblock to solving phantom breaking, but with reports on this forum and YouTube videos showing plenty of examples of non-radar cars doing the same thing, it’s clear that removing radar wasn’t the solution. Maybe a step towards it, maybe a reprioritized change based on chip availability, maybe a decision to save money; but not the fix.
That do not have deployed ~1+million cars with hardware already.But there are many AV companies
Lastly, you seems to be under the impression that with a more expensive/better radar unit the sensor fusion would "just be easier".
That is a known fallacy! Fusing/reconciling signals from very different source will always have its challenges.
The message that Karpathy tried to bring home in this last talk was "are you barking up the right tree" and his concluding slide:
Sensor fusion is the wrong tree!

Using this as an example that Tesla has chosen the right sensor path is a false correlation. It's easy to throw hardware in the car. Only once it's proven working at L3+ is it interesting. In the end this could end up being that Tesla made the biggest mistake, not was the most advanced. Only time will tell.That do not have deployed ~1+million cars with hardware already.
