I have no problem with them enforcing the speed limit…when they change the thruway speed limit to 85 
but in all seriousness, there has to be some kind of cushion in the speed limit because not all cars have accurate enough speedometers to be “right on the money”. I’m sure there is a 5MPH cushion that you can use, but they would never tell you that otherwise people would go 5mph over. I’m not changing the way I drive until it’s a problem…though if you’re in a residential area, go the speed limit.
