<s>[INST] The following problem is not from a textbook, but rather from a real-life observation.

While I was on a road trip, I noticed a speed camera on the side of the road that used radar technology to detect the speed of passing vehicles. The camera would flash if a car was speeding, and I assumed the speed limit on that highway was 65 mph. I passed the camera at a speed of 70 mph, and to my surprise, the camera did not flash. Assuming the radar gun was accurate and I was indeed going 70 mph, do you think the speed camera was set to trigger only for speeds above 70 mph or was it temporarily malfunctioning?[/INST]
