1.56. As I drive to work on my motorcycle, there is one
corner which I go around at a certain speed whether it’s rainy or sunny. If
it’s cloudy but not raining, however, I usually go faster. (SW
original)

1.56 answer: There’s a car wash on that corner. On rainy days, the rain
reduces traction. On sunny days, water from the car wash has the same
effect. If rain is threatening, though, the car wash gets little business
and thus doesn’t make the road wet, so I can take the corner faster.
