Question: how fast can you drive through average speed cameras?
Answer: How do average checks monitor speed? SPECS cameras are often installed 200m apart pre-installed to know that it take about 9 seconds to pass from point A to point B to average 50mph. If you 60, you'll need to do 40 at equal time to average out at 50mph. SPECS 3 cameras can be 75m apart for more accurate readings.
