I agree with all of the posts. There are a lot of variables including speed, the depth of the water on the roadway, whether the road is straight or curved, condition of the roadway, and a lot more. When I think of hydroplaning I think of someone driving on a wet interstate, trying to turn and their car keeps going straight like it is riding on a sheet of ice. That happens often because interstate roads are have a smooth surface and most drivers are traveling at a high rate of speed. When a car hydroplanes the driver has no control except to slow down gradually.

That is a interesting problem with a lot of variables.
