Why do you think Max speed will not be coming back? The ability to dial down speed, or up, is far superior in many peopleā€˜s opinion

There was more discussion about how a cap on speed hurts other actions from the NNs, but they didn't work for Tesla. We do know that Tesla decided it was too difficult to put in this model.

I find it ironic that Elon is keeping us from getting ASS when he has, what? 14 children?
Don’t want to quibble here and my obstetrics experience was very limited but you do know that’s NOT where children come from right?

Does it still have the ability to set either max speed offset and/or speed limit offset?

Sheesh, its both disappointing and refreshing to see such honesty from a product team. "Its too hard" is very to the point.

If it was my project I would find a way to trick the NN into thinking it was going a different speed. Give it more or less frame updates that match the selected max speed vs the speed the NN wants to go. If the NN wants to go 100mph and the user set a max of 50mph, then feed it 2x the frames from the cameras to make 50mph look like 100mph. I am sure that might break it in other ways though.

It really highlights the scary part of humanity's venture into neural networks and machine learning. We do not intuitively understand what is happening inside the black box, and we cannot 100% control their behavior. I don't think it means the machines will enslave or exterminate humanity, but I do think at some point we will lose our ability to address 1 problem without creating 100 more.

Wow that actually kinda blows for them totals away so many different forms of granular control. So that’s 3 separate and distinct forms of speed control that they have removed. Wild.
The options are to set profiles...sloth stays the speed limit and it goes up from there to the highest in mad max, which I've seen do 60 in a 45.

They've hinted they will remove those at some point and want the car to simply drive conditions relative to the limit as with FSDU there will be no preference in speed.

You do realize how insane it is for Tesla to be planning not to allow speed control with FSDU, right? Do they plan on being responsible for every instance of a speeding ticket for the dumb computer system choosing to drive over the limit? This is a bone-headed approach. They need to allow control. The system doesn’t accurately handle the presence of cops parked on the side of the freeway with radars etc. Or complex construction situations or (all of) the places it gets the speed limit wrong either upwards or downwards (such as suddenly thinking it’s 55 in 65 zones). This is a real stupid idea. Their liability for thousands upon thousands of speeding tickets once unsupervised drops, if they don’t allow speed limit to be chosen by the user, is just astonishingly nearsighted. By allowing speed to be chosen, they can still blame the user. With the machine choosing everything including when to speed, that’s legally going to be a liability for Tesla.

It more than likely won't speed with FSDU at all. Completely adhere to the limit. RoboTaxi in Austin speeds (bad at times), but it has a "safety driver", but the delivery didn't go over the speed limit once. I think that's what it will be like with FSDU. Otherwise, yes, Tesla will be getting tickets and bad press.

I think FSDU for consumers is years away, though. FSDS is supervised and you are expected to take over or reduce the speed to not get a ticket.

No ability to choose to speed will also rightly get them plenty of bad press tho. Talk about handicapped tech.

I do think the argument could be made the scroll wheel approach was less than ideal to start with. I’ve always wished it would accept real time corrections. Say that by default it does the speed limit and if you want it to go faster you accelerate to that speed and hold it for a few seconds, then it should try to replicate that cruise velocity to whatever extent possible.
The opposite way is a bit harder logic-wise because applying the brakes is the typical signal to disengage FSD.
Maybe for that you use the scroll wheel to head back to sloth mode and start the speed adjustment process over? I don’t know exactly how I’d do it, but I feel like the most intuitive and precise speed control would be the pedals, because that’s how people drive.

The old way was you could set the exact speed with the scroll wheel. Small clicks were 1 mph, if you rolled it it would jump up 5, but with E2E that went away.

Waymo doesn't speed. People complain about it, but I think it's the safer option.

I totally agree with you. Whatever the outcome, you can be sure that the ticket fines and higher insurance premiums will be baked into the cost of the vehicle/FSD subscription. In the end, we will pay. If Telsas claims of fewer accidents per mile remain true with unsupervised, the insurance savings alone could reduce the total cost of ownership.

Maybe there needs to be federal regulation that exempts approved Level 4 and higher automated driving systems from tickets. Each violation will be a point against them losing certification.
