This makes me realize that what is "direct" and what is "indirect" depends on how technologically advanced the period is.
50 years ago, the cop with this radar gun would never have been considered a "direct"measurement, much less allowed in court. "Direct" speed measurement would have meant timing the car over a measured mile, no ifs ands or buts.
But after 50 years experience w/ radar we now think of the radar gun as a direct measurement.
