Which is great, unless that something is a bunch of murderous hoodlums strung across the road, bent on stopping cars and killing occupants in mid-riot.
Indeed. I have been in situations on the road where an “accident avoidance” system would have killed me.
Regarding touch-screen systems for throttle control: there is often so much valium (delay) programmed into the system to prevent “hunting” that your inputs get muddled by the program, and up becomes down.
I have seen computer programs fighting each other, one set of instructions trying to increase output while a second set of instructions is trying to decrease that output, on the same device.
Using touch screens as the sole control interface in the command & control system on a warship just seems downright dumb. Water damage, battle damage, drop your coffee...
Then, as others have mentioned, there are times you don’t want to have to take your eyes off whatever you are doing to alter your control settings. Touchscreens become a distraction rather than any sort of aid.
