Ithink its more there trying to save fuel rather than just being slow , near £8 a gallon i dont blame them , i know its anoying and ruins our fun , times are hard for everyone and saveing a few quid doing 10 mph less can make all the differance to someone.night or early mornings first light thats the time to wind the bike on no one about air,s normaly calm and you can ride like a nutter as plod is still asleep .
