Frankly this scare the crap out of me. Auto manufacturers are notoriously bad at securing electronic systems that have any kind of software. Also since it is pretty much an open system by design it wouldn't be hard to build a transmitter unit with specious info for the purposes of gaming the system or using it to cause mayhem. I'm all for safety but most of the driving aids have had all most no effect on safety. They just become on more thing to make everyone's most deadly activity require less attention. Doesn't matter if you are not paying attention, the car will stop for you. Truthfully in the US we just need to do what we can to subsidize mass transit. With efficient mass transit, the only people driving are the ones who want to be, and they tend to be slightly more engaged.
