I don’t know the answer to that one
I’ve done some more reading and according to several car experts it’s entirely plausible this was an accident and the fuel line was ruptured causing explosion ..and that explosion on impact (from a high rate of speed) is not uncommon.
It’s odd that no one has reported what he did that day or what he was doing out at 4am . It’s tough to have a fact-based opinion when we have no context.
Just plain weird.
Since he thought the FBI was questioning those around him, and they say they weren’t. There should be an investigation. Detailed autopsy and complete evaluation of car and its black box All results should be made VERY public to dispell speculation
Someone has to know where he had come from and where he was headed.
