I initially thought terrorism, when I heard it was a Bentley, I thought maybe someone involved with the cartels, heard there was a hit out on them, and was high tailing it out of town, not knowing that a bomb had already been planted in their car.
There wasn’t a bomb. Look at the pictures of the crash site, there’s little damage beyond the wreck. A bomb would have done an awful lot more, and there almost certainly would have been other casualties.
