Bit of a shit driver aren’t you? On my advanced driving course very little of it was spent below 100, if the lane was clear about 140 then just slowing down as and when. It was really hard work though, only do blocks of about 45 minutes as the concentration needed is so high. That’s without doing a commentary as well.90 is fine if the outside lane is empty. Above that you have to switch your brain to racing driver mode and it requires too much concentration to do it for any length of time.
It’s all well and good ze Germans having derestricted sections, but have you ever tried driving at 150+? No, neither have I
But I’ve done 130ish and if that speck in the distance slows down suddenly you’re on top of it in a second. You’d be mentally drained after driving like that for more than a few miles.
