Let me address your rural vs. urban cops (disclaimer, I was a rural deputy), urban cops typically have 5+ calls pending at any given time, relatively speaking depending on the day, time, moon phase and city. Backup is seconds/minutes away. They have the option, most of the time to wait for backup before they initiate contact with the individual. They're interpreting the law quickly and doing "micro investigations" on the spot to determine if a crime has been committed and what the "punishment" should be (i.e. ticket, arrest, warning, etc.). Rural cops on the other hand don't have the luxury, in most cases, of having backup close by and their calls could be a 15 min. drive from each other. They have to have more of a "command presence" when dealing with people initially and then they can taper that off if need be based on the individuals attitude towards them. When your backup is 30 min. away, you have to think differently and don't have much room for error. A truck full of drunk dudes could easily overpower you if they wanted to. THAT'S whey rural LEO's are perceived as "asswipes" often. They will mirror the asswipe they're dealing with or the cooperative person they're dealing with. Remember, LEO's are people, with families and as I've said before, they have a belt full of fun tools they're trained to use to ensure they get home safely.
Side note: A burned out tail light is illegal, might want to get that looked at unless you want to meet the entire police force.
