If tesla is a leader in technology why didn't they add something like this to the auto pilot it was added to trains after a few deadly accidents
In Loco, a vigilance device is installed in every locomotive. Loco Pilot (LP) or Assistant Loco Pilot (ALP) have to press a push button switch every minute. This is to acknowledge the vigilance device. If Loco Pilot or ALP are doing other tasks such as increasing/reducing notch, applying brakes, honking horn, operating any switch, etc. then there is no need to acknowledge the vigilance device through the push button. It is automatically acknowledged as the LP or ALP do those tasks.
If LP or ALP are not doing any tasks nor do they press the push button switch(BPVG) of the vigilance device within one minute, then a lamp will glow for next 08 seconds. If anything not done to acknowledge within this 08 seconds a buzzer will sound with lamp glow for 08 (eight) seconds to remind them to acknowledge the vigilance device. If LP or ALP still don’t acknowledge vigilance device within this next 08 ( Eight) seconds, the Loco will apply emergency brakes in train automatically and the train will stop.
