Yes, it actually is (at least partly) a driver bloat issue.
Seriously, go use a computer from like 1995, the mouse cursor works in realtime. Now use a computer today, the mouse cursor has a little light lag, just barely enough to really notice, but the lag is there. Half of that lag I chalk up to the video/GPU driver stack, but still…
Also, PS/2 vs USB?
Yeah, USB has limits on N-Key Rollover. What’s that mean? You can’t simultaneously press any more than 4 keys on a USB keyboard before the computer glitches out and gets confused, yet high quality PS/2 keyboards can recognize upwards of 9 (possibly even more) distinct keys being pressed at the same time.
I was talking more about the priority level of my USB vs PS/2. Not sure why you brought in limitations about simultaneous keystrokes, which has almost as little to do with what I said as this whole conversation has to do with a computer’s reaction time compared to a humans.
Let’s put it in perspective.
Average human reaction time is 250ms. The world record human reaction time is a blistering 100ms.
The Commodore 64 had a 1mhz processors. In the time it takes the average person to react, that machine can run
250,000 instructions, or 100,000 against the world record human reaction time.
Humans aren’t even close to computers in terms of sheer speed, and we haven’t been for nearly 50 years.
Also, while I don’t do flatland BMX or Unicycling, I am an avid gamer and a fire juggler. I think I know a bit about human reaction time… Unless you can demonstrate a human reacting faster than a computer can, then I’m not going to believe any off-side irrelevant weak-anecdotal point you’re going to make.
Congrats, interesting choice of sport/hobby, I hear ya.
That still doesn’t change the fact that the huge driver and software stack these days causes basic simple things like the mouse cursor to lag when same said hardware did not lag 30 years ago.
The same principles apply though, it takes time for the data from the sensors to be registered (and that has to occur over a short length of time to debounce the signal), then it has to be handled by the operating system, rerouted to either AI or complex onboard computers, or both, and after all those time delays, finally output the signals to steal control of your vehicle, to supposedly save your life.
All sounds good on paper, and I’ll admit that the technology generally does pretty well. But at the same time, lag is always a factor these days with digital technology, but I’m right there behind the wheel and ain’t got time to wait on a chip and guess whether it’s gonna correct the situation or not.
These automated vehicle control systems are just allowing people to get more comfortable with their vehicle and pay less attention to the road.
I don’t think the auto braking is AI based. It’s a pretty basic “how fast is the vehicle approaching the nearest object to the sensor” and if that time drops below a certain threshold, it hits the brakes. The computer doesn’t have to steal control of the vehicle either, it just hits the brakes.
Driving down an otherwise empty service road at about 25mph, and some dumbass starts to back out right in front of you when you’re only about 15 feet away from hitting them, then what do?
Slam on brakes, not enough stopping distance. But that gives the other car enough time to back out even further, practically guaranteeing a full on side impact. Both vehicles would have been totalled out.
That’s car logic for you.
Realize there’s not enough time to stop, and if I even tried to slow down, his vehicle would have backed out even further and been right in front of me. So I decided to reduce the inevitable damages by using my steering wheel rather than hit the brakes. So I just clipped his bumper.

You don’t ride BMX flatland or unicycles do ya?

In BMX, you don’t even get 10ms to think. I drive vehicles with the same level of quickness and awareness.
I literally don’t care.

Literally doesn’t matter. Automatic braking systems aren’t moving a cursor around and clicking on the “Brake” button.

I agree. But back to my situation…

That’s car logic for you.
That’s human brain logic for you.
