This is not a conspiracy.
You can see the burn marks on the crash spot. There is video of the crash right after it happened. There is indirect video of the crash including the car hauling A$$ right before a puff of smoke. There are pictures of the crashed car.
Don't turn this into some conspiracy plot because this CLEARLY does NOT fit the description.
I know several people in the racing scene who have died under similar circumstances. Power steering goes out mid run, they crash, fluids spill on exhaust, flames and they paid the ultimate sacrifice.
Tools of war are not always obvious. The worst weapon is an idea planted in the mind of man. Prejudices can kill, suspicion can destroy, and a thoughtless, frightened search for a scapegoat has an everlasting fallout all of its own.
