Two Technnical mistakes...
a. Approaching a curve blindly - He probably could not have seen the banking on the right side. Good drivers with road sense would definitely judge the curve by seeing the left bank, and a general sense of moving traffic.
b. Good drivers know their car - obviously too much speed to be safe in ANY car - let alone a Van. A Van is expected to understeer massively and it did. However that curve is dangerous for most drivers at that speed. Most cars will understeer and RWD sports cars will oversteer, with similar results. I would assume only a very handful of drivers maybe (stress on maybe) can control a regular sports car in that curve at that speed. He is still blind on any car in front of him, so other bad things could have happened as well.
Thankfully nothing major happened.
