So, I'm driving back from lunch just now and this guy on motorcycle coming the other way has his hand out and motioning towards the ground. My first thought is "Who is he to tell us to slow down", seconds later, I found out. He is a very nice guy to tell us to slow down. There was a cop sitting around the corner with his radar gun out and waiting to catch someone.
Sadly, on a normal day, if there was noone is front of me and the guy on the motorcycle had not been there, I would most likely have gotten a ticket. So, thanks motorcycle guy!
