With 1800cc & 160 nominal BHP under your right foot, with the roof down as intended, with the wind trying to remove those last wisps of hair, with all those mad bastards razzing up behind you wanting to race, with continental trucks taking ten minutes to pass you ,whilst filling the car with particulates, soot & other shit related shite, a good audio system is as much use as a loofah to a dredger. I've a 4 x 25watt Sony unit which I can now operate from the steering wheel, JBL speakers all round & A boxed set of three CDs, only one has been in the machine & that's the first disc of 50 years of Fleetwood Mac. I usually get to Albatross & give it up as pointless.
Besides with overcrowded roads & having to play pothole hopscotch, even on trunk routes, concentrating on driving is more important than a sing along or a head banging session.
