@ai6yr I honestly think it's both. Have you seen Tesla cars "brake" for no reason? That little bit of regen braking as the driver re-positions their foot, or whatever they do that flashes the brakes, is probably just enough dynamics to cause hydroplaning in the right conditions.Combine that with the majority of people that hit their brakes when they hit that puddle in the road and get splashy-splashy.Re-Gen braking on low-friction surfaces is a huge problem, when coasting would have been fine.
