I tell you getting up to Arthur's seat is one tedious task, I tried last time and lucky it was at 11pm because I was going so wide on the hair pins, I probably would have hit someone. The recommended speed is 5km/h and I couldn't even hold a line at 20km/h. It's also at least a 45 degree incline, a very intense climb.

And my fuel economy went from ~6L/100 to about ~18L/100 haha xD
