still can spin a big truck and/or turn on incandescent bulbs with temperatures in the thousands of degrees
the internal resistance of lead-acid batteries is in the tens of mili-Ω, the circuit of 2 bolts and one plate/top of the pole would be in the low 100s mili-Ω. lets round up to 200mΩ, power = V•I = V^2•R = 12^2/0.2 = 720W, enough to heat up the top assembly of the pole, and smolder some wood

12 V is not enough to pass through unbroken skin, yes. But 12V has plenty to pass through some bolts and heat up enough to burn your house down.
You may be interested in StyroPyro’s video where he wired 100 car batteries in parallel. Still 12V, but huge current capacity.
