Depending on where you’re at in the States it varies. Around where I live in western NY state they mostly don’t care about speed necessarily it’s more reckless driving. You could be cruising what would be 15-20kph over the limit for y’all and generally speaking the cops don’t give a shit as long as you’re driving for the conditions and with the flow of traffic. But they’ll nail your ass to the wall for half that if they see you weaving through cars without leaving stopping distance.

In a lot of areas I go through regularly they’re way more likely to light you up if they see you brake hard when you see them posted up than if you just cruise past them at a reasonable speed even if it’s technically over the limit. Hell, I’ve had troopers in traffic with me doing what would be like 120 in a 100 in y’alls terms not giving a damn because everybody was leaving enough stopping distance and we were all doing a steady speed not driving erratically.
