Never Use Cruise Control When it's Wet?
Discussion
It's actually been a while since I've had a car with cruise control but I read a shared post on somebody's Facebook that warned of the dangers of using cruise control when the road is wet as the car can suddenly accelerate if it hydroplanes. I am a bit skeptical about this so has anybody heard that this can be an issue and confirm this?
Ah right, so if the car hydraplanes and loses all grip with the road, the cruise control can make it accelerate violently?

My aunt reposted something similar, if it's the same one I think it used some brilliant logic fail about how the wheel spins up to a high speed and as soon as it touches the road the car is launched forward at like 100mph or some equally outlandish speed. Completely overlooks the laws of physics.

Very early systems would spin the wheels up when aquaplaning, but it wouldn't cause the car to shoot forward. However keeping your foot in when aquaplaning isn't the correct response, but whether you'd class the CC as dangerous i'm not sure.

Hydroplaning - or more accurately for cars - aquaplaning, is usually caused by shyte / worn tyres that can't disperse the water fast enough. Nothing to do with the throttle, whether it be opened by yourself, or the car.
I'd say it's a factor of both tread depth and speed, and therefore continuing to accelerate isn't the best response. But as I say, it's not and issue with anything remotely modern.I had an experience a few years ago in a mondeo hire car. Travelling along a dual carriageway at night in heavy rain with cruise control engaged. The car hit a stream of water running across the road and immediately decelerated, before I could react the cruise control tried to accelerate back up to speed and nearly caused a loss of control. Only my extraordinary driving ability saved the day!

If a car was driven onto sheet ice and the cruise control set at 30mph while chained to a large post
how fast would the wheels be spinning? equivalent to 30mph
How fast would the car be traveling? assuming no slack in chain, zero mph. Until the spinning tyres melt through the ice, then all bets are off.
I heard that it is trueish - coming from yank tanks in the 60's with primitive systems. Example in my head is hitting a deep puddle whilst cornering - cruise will give it a load of welly and you'll fall off.If a car was driven onto sheet ice and the cruise control set at 30mph while chained to a large post

Or am I due a whoosh or 2?
