> Brake with a wheel on a piece of cardboard and chances are you'll just slide. Same for an oil slick.

Also autumn leaves. Like sheets of graphene.

It's worth remembering that a car will always brake faster and turn more sharply than a motorbike.

It's also worth remembering that after every rain, the road is slick for a half hour or so while all the oily crap and rubbery crap washes off.
