What keeps these inflation monitors from reporting a false low tire when you are taking a long radius turn on a highway?

This is just a wild guess, but both outside tires would be turning faster than the inside tires in this case, so that information could be used to realize that’s what happening. Also, any car with a stability control system would have sensors indicating if the driver is steering straight or turning.
