Who knew that rain made things slippery?
This one gets pretty ugly, although to our knowledge no one was hurt. Even for the most experienced of drivers, going fast in the rain is a risky activity. Not only that, but cars that have been very well designed to work with active aerodynamics can sometimes feel so planted in the dry that one could easily forget just how badly out of control they can get in the wet. This video is a good example, as the McLaren 650S isn't swerving or anything, and the driver appears to lose control for no reason.
We're guessing that when the car in front of him moved over and the lane was cleared, he decided to speed up and simply put the pedal down a bit more than conditions allowed. It didn't end well.
