Some people have no respect for others and those of us who do, are tired of their crap. 

Now, I don't want to assume maliciousness for what could otherwise be blamed on ignorance, but if you're behind the wheel of your car and you see a semi-truck trying to take a tight turn, maybe you should take your head out of your phone and grab that shifter and reverse. 

Or, you could be like this person and end up getting roasted on the internet. 

What the semi should have done, it sit there until the car was forced to move, but depending on what kind of moron they're dealing with, it could have taken him all day to make that turn.
