Pressure checking is not so rare at least in my area.
Nope, my point is that a pressure warning system is a tool that could be useful, but will be ignored by many and will become little more than another expensive automated gadget t ignore or figure out how to switch off. A pressure gauge will be as effective an automated warning system for most drivers. And it will be a whole lot cheaper.
Unfortunately there are a lot of drivers who have conditioned themselves to routinely ignore the check engine and engine warning lamps as well as the text messages that scroll across the dashboard display. Like the many people who continue to run out of gas after the needle has passed into the orange area AND the red warning light has gone on.
Quoting you: ...are stiff enough you can't visually "gage" the tire pressure. It is not possible to visually gauge tire pressure with any reliability under any circumstance period.
Really now. If handheld gauges are that inaccurate then how useful or accurate can we expect a pressure sensing system to be. Remember, it is nothing more than analog sensors rigged to a digital display. And how can a driver rely on such a system if it goes out of calibration with no warning. I've checked several different handheld gauges and they are plenty close enough for maintaining reasonably accurate pressure.
Your experience does not appear to be the same as the caddy owner - strange isn't it. Come to think of it I have never had a handheld analog gauge go out of calibration.
That's an "unusual" way of dealing with life, wouldn't you say?
