At high speed in slippery bends they provide only a few square centimetres of contact with the road, yet they help a driver steer safely around the corner.
As you follow each and every twist and turn down Highway One, you too will be lost for words, for this is a place that often defies the limits of language.
The port of Manham is located in beautiful and peaceful countryside, on a bend in the great River Avon, and developed here because it's the highest navigable point of the Avon.

And then, at last, as he crept around yet another bend, he saw a solid wall ahead on which two entwined serpents were carved, their eyes set with great, glinting emeralds.
We've done some experimentation with tire pressure and for rolling speed, I'm not certain exactly the correlation between pressure and speed, but I can definitely feel a difference in the corners with different pressures.
But I mean, we all love like race car drivers and just like being bank going around that curve at a high speed being pushed into your seat, and it's like music.
And, in a more practical vein, engineers in the autonomous-vehicle industry would be keen on a technology that let their cars spot other motorists blithely speeding around blind corners.
