I don't agree. For those of us who understand cars it seems like a redundant technology. However, for the vast majority (my wife included) would have been driving around on unsafe under inflated tires if it weren't for me checking them. Now she gets the low pressure warning and it freaks her out enough to go get them topped up or looked at for a leak. If it saves lives, no matter how few, I don't see it as a cash grab. People said the same thing about ABS brakes when they first came out...
