That's very true TT and I always use the indicators in the car but back when I was 17 I took an advanced driving course at the instruction of our MD E Lambert ,at Horsman 's ,He was also chair of the Liverpool and Wirral road safety thingy and also heavily involved in setting up tests for driving instructors .Crafty old sod he also got a hefty reduction in the block insurance for the company if everyone attended and passed . It was impressive and included use of the police skid pan ( great fun ) the lessons learned there alone stay with me even now ,the night driving part was a great experience to. Most importantly the instructors,mostly ex police ,made you think ahead and be "aware" of them ,they taught that your vehicles position on the road should be enough, without indicators, to make other road users know or have a fair idea what you intended ( that was also in the police drivers handbook which back then was "roadcraft " if memory serves) Of course that was in 1967 traffics increased, drivers have dumbed down but a lot of that info is still retained ,is still pertinent today and as served me well.Bob
