Luddite ..... hitch-hiking with a mate of mine when I was in my early teens we got a lift from an American guy who had bought a VW microbus and was touring Europe and the UK before shipping it home ..... simlarly, we got behind a gravel truck which had a big cobblestone between the rear tyres .... which promptly flew out and hit the screen right in front of me in the passenger seat .. . Dished the screen in like a big soup plate .... to this day I believe if it hadn't been a US spec with the laminated screen but a UK spec with the (then) ordinary toughened glass screen I wouldn't be here..... I still check every twin wheeler I follow as a reflex !
