this happened last year I was driving home after picking up a couple oz of weed stopped at a traffic island when I was hit from behind and shunted into the car in front and as shit happens a police patrol car was coming around the roundabout and offered me some help a male and female officer got out the car and gave me a hand move my car the female officer who was standing quiet close said whats that funny smell to which I replied cooling fluid she just gave me a funny look and continued to follow me around the car inspecting the damage,,im sure she knew what the smell was made me sweat though
