Some of the drivers who use the 75 - how shall we put this politely - have absolutely no respect for the rule of law. If the law says 40 mph they will do 50 just because they can - limiters just made to be disconnected . Now put 6,8,10 of these lads together in a hurry to get to their drops in "the bean " or back up the road to a boat. Do you really think playing road commander with these guys is going to win you any prizes?
Do yourself a favour and get into a layby and let them past otherwise youll end up losing your wing mirror if your lucky , if your not so lucky youll end up with youre own little layby for one in the nearest field .
I’ve been up and down the 75 for nearly 20 years its simple go flat out or get out of the way - holding up a pack of V8’s in a hurry to get somewhere isnt a good idea .
