I drive down to palm beach every other weekend and the last 2 times I have been followed closely by cops in marked and unmarked cars, I was driving with the traffic both times and that means upto 10ks over the limit, both times they sat behind me for a while (shittin bricks I was) and then drive up beside and look in, then drive off. I can only assume that they have done a licencse check, looked to see it was actually me and that I am not harmful to society and thankfully leave me be, I tend to think if I was 20yrs younger I might not be so lucky though.
