Any company that went into that business would be sued into oblivion the first time a drunk driver with a disabled device killed someone.
Valid point...but...who gets sued if the device fails to operate properly even if it was not tampered with?
Or, who gets sued when the device interrupts the starter on a false positive and someone dies as a result of transportation being out-of-service?
In the face of all these questions and your statement, it looks as if the only parties who will benefit from this legislation becoming law will be the lawyers. It's a win-win for them.
