Most of the time, it's a waste of time trying to talk your way out of a ticket for speeding or other driving violations. Police officers have heard and seen it all before. But sometimes, it actually works.
1.) From PressureAwkward:
I had a cop laugh in my face when I was 19 and got caught speeding.
I was doing 75 on the highway at night, in an area that has signs that indicate the speed limit is 70 during the day but 60 at night.
I legitimately didn't know I was speeding because of of this incident when I was a kid... my dad was kind of a speed demon, and I was a snitch of a kid. One night on this same stretch of highway I looked over and saw him driving about 80, and I pointed out that the sign said the speed limit was 60 at night.
