It looks like missile footage, except with a slow explosive with fire rather than a fast explosive with shockwave.

This particular video looks like it destroys the white car, but other angles of the aftermath show that the white car was a bit behind the explosion and that driver was OK but understandably shaken up.

NGL. I've seen other ways to die. Instant obliteration isn't a bad way to go. Beats drowning by a long shot.
