Gas tank explosion.
Quite!
Though you can see in the video immediately before anything happens to my vehicle they are coming up the ridge behind me.
And based on the angle / distance between the two cars I cannot see how the tank / wheel was exposed ?
That is why I have the theory there might be some weird desync going on, where, on their screen such a shot was possible and that was what registered.
It'd be interesting to see what happened from their perspective.
I honestly don't know enough to say - but the whole thing was not something I've experienced before =)
