Disclaimer: I really don’t care if someone is going even 5 mph below the speed limit, but anything greater is irritating and a safety issue. 

So whenever I get on the highway to go to school about an hour away, I come across tens upon tens of extremely slow drivers. To get a sense of how slow they go, I will be in a 70mph zone and they will be tearing asphalt at ~50/55. This is ridiculous and completely unsafe, and so I honk at them. Am I an asshole for doing this?
