You've absolutely not seen the video. You're not wrong, if a car is coming, get out of the way. But the car is travelling fast around a curved part of the highway and the vehicles blocking the road are sideways so the lights on his car wouldn't have reflected off the side of the vehicles until it was too late to slow down, which is what we saw happen, he immediately reacts and avoids the van and there's people placed behind it.

The people also very clearly were running to get out of the way in this situation.
