I received this at work as our monthly safety tip. It doesn't make sense to me, but I thought I'd ask the pros!
==========
Cruise Control in the Rain?

A 36-year-old female had an accident several weeks ago and totaled her car.
It was raining, though not excessively, when her car suddenly began to hydroplane and literally flew through the air.
She was not seriously injured but very stunned at the sudden occurrence! When she explained to the highway patrolman what had happened he told her something that every driver should know: Never Drive in the Rain with Your Cruise Control On.
She had thought she was being cautious by setting the cruise control and maintaining a safe consistent speed in the rain. But the highway patrolman told her that if the cruise control is on and your car begins to hydroplane—when your tires lose contact with the pavement—your car will accelerate to a higher rate of speed and you take off like an airplane. She told the patrolman that was exactly what had occurred. We all know you have little or no control over a car when it begins to hydroplane. The highway patrol estimated her car was actually traveling through the air at 10 to 15 miles per hour faster than the speed set on the cruise control.

OK... I can see the drive wheels quickly accelerating when they lose traction, but accelerating the car 10-15mph faster??? When they are not in contact with the road??? That part just doesn't add up in my mind. Maybe my Physics 101 is out of date...

Email is like giving every little kid a doorbell to ring. Some kids never grow up. If she was hydroplaning that bad she would of had more since to take control of the car you'ld think. I dont believe it since modern cars get the speed from the trans and if she was hydroplaning she would of slowed.
It's about at lame as the kids who make videos of their speedometer acting like their car is all souped up when the wheels are just spinning on leaves or ice.
If the story is true I've got some real good stories for patrolmen that might pull me over.

This ones been around forever and the point of not using the cruise control during inclement weather is valid but the example is not...

If your safety department has any sense of responsibility they will start investigating their data before presenting it in the future.

Forward this link to your safety dept http://www.snopes.com/autos/techno/wetroad.asp Ask them to read past the the "True" status given...

Traction is what excelerates a vehicle, not the loss of traction...

I've seen that very email before and if you touch the brakes, it will override the cruise control!
Sounds like she was going too fast to begin with!!! I guess I have LOTS of experience driving in the rain (being from Seattle and all ;) ) Anyway, safety should always be our first priority, I just wouldn't think using cc would be a big deal...

Thanks gang!

I have heard of that site but never visited it. Glad to see that the laws of physics have not changed over the years. :D

Using cruise control in bad weather (limited traction) situations is not a good idea. It can cause a loss of control. The example given was a little ummmmm exagerated (how's that for PC).
