I would think there is some truth behind that. For starters not all cars have ESP. So if the speed drops below the one set on cruise control, for example going up the hill or car being slowed down by hitting deep puddle and cruise control starts to accelerate and there is very little grip like on ice it could start spinning wheels and loose control. If you have wide tyres with low tread and sufficient speed that could cause aquaplaning and loose grip as well. I would say it is unlikely but given right circumstances possible, more likely on big engined rear wheel drive cars with little weight over driving axle. Maybe we should write to Mythbusters and ask them to test it.
