In Ontario, Canada with our RIDICULOUS "Street Racing" laws the cop is judge, jury and executioner on the spot! Your vehicle is impounded and even if you later prove your innocence you are still "on the hook" for towing and impound fees and you have had your licence suspended even if you later proved that you had done nothing wrong.
"Street racing" includes 2 or more vehicles accelerating or travelling very quickly together, 50kph over the speed limit even if you are by yourself, spinning or even chirping tires and wheelies on a motorcycle.
Canadian Constitution (same as with U.S.) indicates that a person is innocent until proven guilty... but this is NOT the case in Ontario today!
If any State tries to bring in similar legislation to this... FIGHT IT!!!
