In my own personal, non-objective observation over several decades,
unless the vehicle stops, fifty percent of the drivers in my household
will not notice any dashboard warning indicator, and continue to drive.
Speedometer and fuel might as well be the only gauges. Everything else
is completely ignored, including the red light that indicates the
parking brake is on. And, as it turns out, the car has enough power to
make complete trips in town and on highways while overcoming the
influence of said brake. On multiple occasions. Apparently the decreased
acceleration was not noticed either, or the smoke from the rear wheels.

I guess the point is, no tire pressure warning system will be 100%
effective, so there is no need to make it 100% accurate.

Even if they made it so the car needed an override button be pushed to
start the car if there was a warning indicated, some drivers would just
get into the habit of pushing that button automatically and continue to
ignore any alerts.

Cheerful regards,

Bob
