Did you report this to the police, it sounds like the guy may have done it on purpose, and if he did, he may have done it to others, you may be able to find his license plate number from that.
The Police can make a note about it at any rate, they can watch for reports about a White SUV taking out Motorcyclists, so the next time it happens, there may be more information.
Short of wearing an athletic supporter when riding, there isn't much we can do to protect ourselves down there for this kind of crash. We are sitting legs open on top of a tank of gas and flying into a whack of instruments.
Get well soon.
