I was once pursued by an alien space craft that had flashing red and blue lights. The pilot had taken over the body of a state trooper and gave me a coded message of some kind. I sent it off to be interpreted along with a healthy fee. Fortunately I suffered no lingering effects from the ray gun he used on my car.
Legend has it that a car, just like the one in post 41, was able to out run two of those alien spacecraft you speak of ;^)
You know, I had the same experience once, but the alien in with the badge said the speed limit drops from 55 to 40 when you enter the city limits and to be more careful next time. I didn’t get any coded souvenirs though.
