Montana raised the speed limits from 75 to 80mph last summer. I've noticed an odd effect... the traffic is now predominantly moving between 75 to 80mph, not 75

- CamperBob2 11y agoThis isn't an odd effect at all, it's perfectly well understood. Google the "85th percentile rule" for more. If most drivers are "automatically" adding 9-10 MPH to the speed limit, it means the speed limit is too low.
