I agree its stupid but sometimes man juice kicks in,I drive a 90bhp 1.3 cdti astra van daily and you always get people hanging on your arse so I either brake harshly or show them on the lanes power is nothing,I do 100 miles a day which consists of 60mph single lanes,my problem is old folk who are clearly living in the 60's that plod along at 30-40mph,so yeah I drive like a dick quite alot but after a 10hr shift stuck behind someone who shouldn't have a license gets a little frustrating and I have zero patients which is hard living day to day,and my last point is when you next go on the motorway look at how many people indicate to switch lanes.its like this rule has been erased,did 30 mile on the a55 yesterday and no BS I must of seen maximum of 3 cars indicate,big headed or not I can drive fast safley but what makes it dangerous is the other people driving with very little experience
