Doesn’t it make sense to slow down when the roads are wet? Not panicking like the average Capetonian at the sight of rain but to generally proceed with more caution than one would on dry roads.
That said, the driver of the Opel Corsa OPC in this video appears to be driving a lot faster (while in the slow lane) than the road users around him. Reacting the equally questionable actions of the driver of the MPV, the Corsa driver appears to lose control under braking before veering across the road and making heavy contact with oncoming traffic.
We hope no one was too seriously injured.
