I've not yet seen Peter Hickman look out of place/road(Steve Plater looked more "edgy" in a couple of places back in the day) out there and his speed increase has corresponded in a proper fashion with each additional year of competing, with ref to the Rhencullen/Hickman thing I was watching just before Rhencullen at the end of Kirk Michael for the Senior, PH caught the group of riders right there, throttled off on the approach gave them enough road and although I couldn't see the exit the way he set them up and with his speed differential would have passed them easily and in context safely, even at those speeds a slower rider does not just appear right in front of you, you'll normally catch a glimpse/reflection somewhere ahead and it's then down to setting them up and overtaking with superior exit or approach speed rather than riding up behind them scrubbing off loads of speed.
