The fallacy of this kind of thinking is that the resistance enters the formula. With 12 Volts and normal skin resistance being in the thousands of Ohms the current able to pass is in the tens of microamperes. This means you will not be able to pass high current thru human skin with 12 Volts (high current being defined as amperes).
In other words, 12 V won't hurt you. If it could harm you there would be warning stickers all over the battery and the area around the battery and the cigarette lighter and every place like in an electrical breaker box or switch panel.

Electrical safety classes state that voltages above 24 Volts are considered dangerous.
The statement/warning about jewelry is very applicable when it comes to a storage battery however.
