First off, the ping rate for auto traffic is an enormous number of pulse durations or return times -- the radar will ignore returns coming back more than a couple of microseconds after it sends its last ping, and only needs to ping every few tens of milliseconds. That's a window of less than 0.1%.
If a car detects a return in a "forbidden" time slot, it can just switch to not using that frequency. Or use the kind of random backoff that Ethernet has been using now for forty years.
And that's just two solutions.
