In rural America, one can get a battery powered electric fence charger for
under $40.  If you built a cage out of insulated rods where eachrod
alternated between ground and HOT, you should be able to fix up a nice
shield that wont kill the sensitive electronics in your auto.

I use one such charger on a fence around my pasture to keep the cows and
horse in.  My kids have a knack for turning it on while I am inside it.  I
have been barefooted in mud and been hit by it, (more than once) and lived
to tell about it.

I controlled tests (which obviously were not well enough controlled) 12
volts DC applied across the chest of a volunteer caused death. This would be
exceptional but is obviously possible. DC and AC produce somewhat different
results but the safe conclusion is that any HV shocker COULD cause death.
YMMV.
