Did you mean kV? I don’t know if 40kHz is high enough, but I know at some point it doesn’t even shock anymore, just burns. Hence you can take a screwdriver in your hand, and get it close to high frequency Tesla coil / slayer exciter circuit (not that I know the difference) and have it flow through you no problem, just if you touch the spark directly it burns.
A car battery would not do much. Let’s try 40kHz AC?
