Exactly. The FCC has rf safety guidelines that all rf emitters need to meet. Even us ham radio operators are supposed to do an assessment of their own stations. I'd like to see what kind of field strengths they are talking about and at what frequencies and distances.
Also.... having some familiarity with CAN bus and auto electronics, I'm wondering exactly how they can say that their pulse generator only applies the brakes and makes the radio wacky. Why wouldn't some random disruption cause, say, the fuel injection system to go to full throttle? Or maybe the brakes on only one side of the car go full on? Or the automatic transmission to start shifting randomly?
The validation test matrix for this kind of device is impractically huge, and the safety implications of a missed case are severe.
