Re road rage.
Im of the belief you dont start trouble with anyone on the road.
Similar to any other part of life really. You start trouble then you better be ready for consequences.
Easy to pick on the wrong person. End up in a ton more than you expected.
Someone cuts you off you back off and allow them to complete there MISTAKE.
I would even give them a thumbs up and smile to say all good, mistakes happen sort of thing.
Someone wants to be a dick in any driving condition you let them do it.
They intentionally drive slow infront of you? Cool drive slow behind but remain a good safe legal distance, turn up the radio and enjoy the drive.
No point getting angry or upset. Just screws you own day. Even if said dickhead driver does something that requires you to take evasive action.
I recently reversed out my driveway and took out my recycling bin. In front of a couple of people i dont know. Im sure they think im THAT DICKHEAD. Yet generally speaking im a good driver.
Final point. We all make mistakes at times on the road. Mistakes that others could see and assume your the dick. Yep Mistakes happen.
