I like the TPMS on cars where the driver is unlikely to ever check the
tire pressure.

Is that your car? I don't have TPMS on my car, but I keep a tire
gauge in my glovebox, and occasionally check all tires.
If leakage is excessive I get it fixed. That seldom happens.
If I had TPMS and it worked, I would do the same, less the check.
I haven't had trouble with tire wear.

Sensors are going to be used in increasing number on
vehicles and machinery for faults and to indicate when maintenance is
actually necessary (versus the present system of basing maintenance
mainly on time or miles).

Oil change is the only one on my car. What others are available?
I don't understand this sudden interest in nitrogen.
Tire Rack says:
"Overall, inflating tires with nitrogen won't hurt them and may
provide some minimal benefits."
"Rather than pay extra for nitrogen, most drivers would be better off
buying an accurate tire pressure gauge and checking and adjusting
their tire pressures regularly."

Doubt I'll ever put nitrogen in my tires.
None of the "minimal benefits" even apply to me, or most drivers.
But if it's free I won't turn it down.
