Very funny, really. I've got 8 other motor vehicles, and none of them have this system. Never wrecked, never stranded, and never ever even thought of suing anyone over tire failures (0) due to low pressure. My one and only blowout was in 1972, in a '62 Corvair. Going around a curve. At 60. Rear tire. I survived, as did the 'Vair. This is simply something like cellphones, every one wants it, no one really needs it.
