Well , like dave said :   I don't want to be the guy "Holding - up " traffic ... BUT ... If I'm doing the speed limit  ... then I'm NOT holding - up Traffic  and  I'm NOT SPEEDING EITHER , I'm doing the RIGHT THING .   What other folks do ... I'm not in charge of .    
But I do keep an eye on my mirrors  to watch out for crazy people behind me even when driving the truck !  

Just drive the Speed Limit and Play Nice works just fine for me !   I've been told that in Germany "Speed Cameras " enforce the speed limits and tickets come through the mail.  
Just think of all the $$$'s that could be raised and how low Gas tax could get if we did the same as Germany ?   And how much safer the Roads would be .     Shame on American speed enforcement efforts !!!  

There are so many nice bikes out in the World that we don't get here in the USA !  

I saw a U-Tube report on a Yamaha BW350 tonight , air cooled single .   It was spinning the tire and jumping dirt piles in regular Yamaha fashion and looking good doing it.
