Wasn't it also Grosjean who stuffed it in the fence under SC in Hungary in 2014?
If you discount starts and restarts, there are probably more incidents per lap under SC than under green flag conditions (possible exaggeration, I don't have the figures). I'm not a fan of the SC because it disrupts the race almost as much as a red flag but is far less safe. It's also used for many incidents that could be covered by a local slow zone, which would alleviate the tyre warming dramas which are the underlying cause of most incidents that happen under SC conditions.
If you slow the cars down over the entire lap even though the incident is localised to one corner, then you make it very difficult for the drivers to hit their deltas precisely whilst at the same time maximising the amount of heat they generate in their brakes and tyres. They have to find ways to make wheelspin, keep working the brakes and generate tyre slip, all while in maximum harvesting mode and therefore experiencing variable amounts of engine braking at the rear axle. Ever likely they sometimes get it wrong and end up in the fence.
