Disclaimer: I am not a cop. These may be laws. These may not be laws. I don't know. Either way, they should be enforced more or be turned into laws.
1. Cruising in the left lane
Nope. Don't do it. If there is nobody around you, get your car back into the right lane. If there is someone clearly trying to pass you in the left lane, get your car into the right lane and stay there. Shoutout to that one cop who pulled someone over for holding up 20 cars in the left lane.
2. Breaking before getting into a turn lane
Ok I do realize sometimes you have to, but if there's enough room to start breaking after you have merged into a turn lane, please do! Don't start breaking on the highway or road because then you slow everyone else down. And it's kind of dangerous.
3. Not using a blinker
I don't even have to explain this. The only exception would be if there was nobody around you.
4. Driving under the speed limit
No one likes to get stuck behind a driver who refuses to drive as fast as the speed limit.
5. Knowing a two lane road turns into one, then cutting everyone off
If you know a two lane road is going to be a one lane road, don't be a jerk and speed all the way to where it merges into one and cut off everyone.
6. Driving with two feet
If your brake lights are on... while you are driving full speed... you clearly need to just sell your car because you don't know how to drive.
7. Texting and driving
If you can't go an entire drive to wherever without picking up your phone, you have an addiction to your phone. Stop. Texting. And. Driving.
