I have news for you Joey Chitwood type that are planning on laying your
Vans on their roofs.

The batteries falling out of their mounts, or leaking acid should be the
least of your worries.

I would assume that you'd be thinking more about "how in the heck am I
gonna get outa here ASAP" than worrying about the batteries.

If your really concerned, I'd be pondering a roll cage design first.

I think the gas pouring out of the tank would be the first thing to
think about.

The battery acid malarky would be way down on the bottom of the totem
pole.
