Tesla Cyberpuke

[Beany]

Fiver says he was paying absolutely no attention to anything around him Because AutoPilot, shat his pants when the car beeped at him and made the initial move, then he probably responded by mashing and sawing at the wheel like a five year old with a Tomy Racing Turbo toy.

But he's evidentally invested his entire personality into Tesla, so it can't be the car at fault.

Likewise with respect to the camera footage. I find it believable that he didn't think to grab the USB drive from the car post-crash, but I am Pressing X To Doubt on the incident even being necessary, given how regularly the Tesla camera systems poorly interpret depth/distance thanks to the lack of LIDAR.

Blimey. Sorry about the muzak.

[Mito Man]

That's not lag, or is the person on X being intentionally stupid?

[Beany]

The wheel directional motors can't keep up with inputs. I sort of assumed they would be able to.

So yeah, I'd call that lag. It's lagging behind the inputs.

[Mito Man]

Wheels on car start turning immediately, therefore not input lag - obviously they can’t keep up as the fly by wire system allows minute movements of the steering wheel to equate to full lock to lock movement of tyres when below 10 mph.
It’s not Forza on a joystick ffs.

[Beany]

Yet in my car, if I whip the wheel around, the steering gear doesn't take half a second to catch up.

Doesn't matter how you term it, it's lagging. Nature of the beast with how they've set it up.

Obviously, it's pointless in the real world, but that's not going to stop me pointing and laughing at the Cybertruck.

[Mito Man]

I’d like to see you film a video with you spinning your steering wheel lock to lock in 1/4 of a second.

Yes.

Thats why it’s so fucking stupid.

Steering linearity and laws of physics.

but there's a lag behind the steering wheel input and the wheel turning. Just because it allows you to turn the wheel far faster than you could in a conventional hydraulic/electric set up with a physical steering column, doesn't mean it's not called lag.

[Sundayjumper]

Mito's brain is lagging.

He'll get there eventually.

When you press the brake pedal and your car doesn’t instantly stop, is that lag?

when you press the brake pedal, the pads move against the disks without lag (or certainly with very minimal lag) because it's a hydraulic system. That's why you bleed the air out, so there's effectively a "solid" (even though it's liquid contained in pipes) connection between the movement of your foot and the movement of the pads.

The brakes act effectively instantly and grab the disks, the rest of the car then responds in line with the forces applied - the car is lagging behind your input, not the brakes themselves.

This is the vehicles steering system failing to keep up with user inputs. That would be like if you pressed the brake pedal, and they don't grab the discs for half a second.

And when you turn the wheel the motor for the servo is giving 100% torque instantly (granted, yes, there will some imperceptible lag in the form of electricity going to the ecu and motor) but it’s not going to turn the wheels 45 degrees near instantly in the same way a car won’t stop instantly. But I wouldn’t call not getting to full lock lag. It’s not like a turbo spooling up. When he flicks the wheel in the opposite direction it instantly starts turn the other way.

[Sundayjumper]

This might actually be the stupidest argument we've had on here. Which is a real achievement.

[Rich B]

To take it to its extreme, with a delay between how fast the driver car turn the steering wheel and how fast the front wheels turn, this probably wouldn't have ended so luckily.



It would be interesting to see if the cyber truck lag can actually be felt - I suspect the fact it's a big lumbering truck with big tyres means you never could.

if the output isn't turning at exactly the same time as the input - there's lag.

The input and output on a normal steering system are connected with a big metal pole which means there's no lag.

This video clearly shows a delay (or lag) between the input and the output.

I don't think we can explain it any more?'
