A controversial figure to be sure. One of the discoverers of shale oil. Indicted for bid rigging.

I suspect suicide by car.
 
Sad story. The timing and circumstances do suggest it was an intentional act.

Also, the extensive damage to the car.

Obviously, a very intelligent man but he had a fatal flaw. Rather than face justice he decided to check out. Also, no criminal record now.

Trust me. When people want to commit suicide, driving ones vehicle into a concrete wall isn't normally the first choice.
