this happened by me last summer, got caught out 3 times in a week, eventually the guy with the laser just starting waving hello
never got a letter though
just drive up the kerb and run em over, you can claim you thought they had a gun !
in a nutshell " GET A LIFE !!!"
IF THEY WANT TO DO THIS OUTSIDE A SCHOOL ETC ...GREAT ! BUT THEY WERE ON A BEND IN A 40MPH ON A HILL ON A WIDE OPEN ROAD !!! FFS
