I was travelling home yesterday evening in the busy Friday night traffic. In front, was a dark grey 2017 BMW M5. I could sense that the driver was somewhat frustrated as he was right up the bumper of the car in front. When a short gap appeared in the oncoming traffic, he took his chance and floored it, passing the two cars in front, before having to dive back into the continuous stream of traffic. That was the only chance he got to use the blistering performance of his M5. So, as you say, all rather POINTLESS. I would relish owning a performance car like an M3 or an M5, but I think the frustration of not being able to use it, would drive me scatty.
