Motoring for the hard of hearing?

Spotted in Llandod this morning; it was outside Aldi, so that partly explains it (incidentally, love the shop, can’t stay away!).  Out-car stereo?  Personal communication system between him and his wife – “hurry up in there!”.  Should’ve gone to Specsavers?  Warning – small vehicle reversing!  As his wife was heard to say, “he’s very good with his hands, saves us pounds with his DIY”.
