Having a system tell you in real-time what the pressures are is somewhat irrelevant unless you are competing in professional racing and have a team at hand who can provide your real-time analysis and feedback on a per corner basis (aka, F1).
As a driver at a track day, the only thing you can do is slow down, back off or stop and adjust pressures. If the current technology doesn't do enough to equip you... well, need I say more. For track days, even timed laps, this just comes across as a massive gimmick designed to sell more tyres (and at a higher price).

I tend to agree in part... I think the most valuable data is the Michelin evolving database behind the tire pressure recommendations, not necessary the real time data. Is there anywhere to get that info??
IF the pressure adjustment recommendations are accurate, I see how this could be a useful tool to get the most performance and longevity out of the tires based on the specific track and conditions.
I thought the most interesting part of the video was that the temp/pressure monitor was Green at 2.65 bar - It seemed like the recommendation was to drop to 2.4 bar, not sure. I would bet that is more pressure than what most people run with these tires on their M2.
For me, by the time I can accurate pressure readings (iDrive is always off by 1-2 Psi in my car) at a track day, I have already done cool down laps. And once I get those pressures, how do I know what the best adjustment is other than subjective trial and error... 'What tire pressure should I run' discussions seem a lot like 'what is the best oil to use' discussions...
