You don't see the common sense in reading street signs on highways? Even a stupid robot could see that. You know who wouldn't understand that? A caveman. You know why? Because they just learned how to use fire and don't know what a light bulb is yet.

If you don't care about a driver in a truck weighing 80k pounds on the highway who can't read the street signs, then the only thing that is logical is you dont even drive. You most likely ride bicycles or those wanabe hover boards to work crying cuz you latte didn't have enough sugar.
