why is the speed limit set at a speed that most people will surpass by 5-10 mph and not get pulled over? Is there a reason they don’t set the limit 5-10 mph faster and actually enforce it strictly?

I think the practice exists because that 5-10 mph helps compensate for normal fluctuations in speed (up/down hills) and precision in instrumentation (worn tires, viewing angle of the speedometer, variations in the radar gun) and the police generally don't want to issue contestable tickets. That's…

The Short Answer

I think the practice exists because that 5-10 mph helps compensate for normal fluctuations in speed (up/down hills) and precision in instrumentation (worn tires, viewing angle of the speedometer, variations in the radar gun) and the police generally don't want to issue contestable tickets. That's not really a reason why people shouldn't manage their speed to not exceed the limit by building that buffer in to their cruising speed. But since it's ultimately the officers decision if they will issue the ticket, it's technically their decision to grant that buffer.
