Hi, I'm new to this forum, but I've been a new 5 series driver for 11 years. Can anybody tell me why BMW insist on using the same inefficient windscreen wiper system? I find that they take ages to start regardless of where the wheel is and on a slight must, they're going at top speed. Also why is there no interval option while moving? It's enough to make me not buy another B'mer. Any thoughts?
