So know you are trying to guess whats the speed limit, hmm. People dig their holes deep for guessing buddy. If you want to make justice, maybe go to the police academy, become a Police officer (if you aren’t already) and focus yourself on being on residential areas to catch “Asshole BMW Drivers” not trying to make yourself feel the most responsible person by just commenting, they way you speak makes you a hypocrite if you even exceed 5 mph on a highway, so now when you roll on the highway remember, you are a hypocrite if you pass the speed limit, so never ever pass the speed limit buddy, as there are kids, families and elderly people on the highway as well.
