The hacking is one thing... but the fact that each pressure sensor has a frickin' unique ID which it's sending out via RF to all passerby is just about as bad.
It means, for example, that the police could just setup a box on the side of a particular road and get a nice timestamped list of everyone traveling past the box.

I never thought about it before, but that makes sense. It should be possible to turn it off, however if it's like bluetooth, depending on the power, the range can be made extremely short. In that case you could'nt be hacked or tracked by anyone who's more than 10 feet away.
Still legal in 16 states. It's happy. It's fun. It's Happy Fun Car.
