The Q2 doesn't like aquaplaning in my experience, even if just briefly over a puddle. Get a more pronounced tug of the wheel going over standing water on one side, both sides and it will transfer drive from one wheel to the other searching for grip. Definitely unsettling when traveling at around the speed limit (~110 kph). In conditions where there is a chance of aquaplaning I'm forced to go slower than I would without it that's for sure.

Best way to combat it is check the tyre pressures and take it easy as suggested.
