Not intuitive, but on pushbutton ignition systems you can push and sold the start button to kill the ignition. Sort of like M/S Windows.
are your really that dumb?
If your computer HANGS (and shutdown does not work for example), the RESET/POWER button on the computer is HARDWIRED to restart the computer, and it takes seconds/minutes to do so!
So IF the computer is doing something important like, oh, say running your pacemaker or monitoring nuclear equipment, then you may be VERY DEAD.
There IS NO HARD “OFF” on the “push button ignition systems”. The very fact that they are computer controlled should tell you this.
Would YOU GET on a plane run by a WINDOWS computer? Not even Bill Gates would trust windows to run a plane he was riding on.
