To start off: I was explaining to my friend that I don’t have a grounding point in my house (plumbing is PVC, outlets are gcfi protected only, not allowed to drive a grounding rod into the ground, etc…) and that I’ve just been handling sensitive electronics with just luck and preparation (humidity, moisturizer, no synthetic clothing, etc…) all this time. He told me to just wire myself to a good, multimeter tested, grounding point in a car and that will discharge any built-up static electricity. I’m not smart enough to argue with him on this subject but that doesnt seem the safest. Would that work or should I just keep doing my method? My understanding is that chassis grounding is essentially replacing wires with the frame so the outcome would just be connecting myself to the negative terminal of a car battery.

Tldr: I’m explaining my lack of a grounding point at home for sensitive electronics and is advised by my friend to wire myself to a grounded point in a car to discharge built-up static electricity. However, I’m uncertain about the safety of this suggestion and questions whether my current method of handling electronics with precautions is sufficient.

Edit: lmao people are really getting hung up on the no grounded outlet part. Umm my best explanation I guess is that its an older house that had 2 prong outlets and was “updated” with gfci protected outlets afterwards think the breakers as well. My understanding is that its up to code but I’m not an electrician. As for the plumbing I’m sure there’s still copper somewhere but the majority has been updated to pvc over the years. Again it’s not my house I don’t want to go biting the hand that feeds me. Thank you though, haha

Edit #2: thank you all so much for the helpful advice, I really appreciate all of you!

    An electrical ground is reservoir into which you can dump charge with altering its potential difference. A car, in and of itself, is ground for the small shocks that occur from static. The earth is a bit overkill here.

    Edit: I am about to use the word “safe” on the internet. Normal “don’t trust everyone on the internet” warnings apply.

    You are correct that connecting yourself to ground of the car is the same as connecting to the negative terminal. You should be safe doing so in a properly wired car.

    That is to say, unless you expect to be at different potential differences. When might that happen? In a lightning strike for example. You do NOT want to electrically connected to your car’s ground in a lightning strike. (You should be perfectly safe inside the car, not touching the car’s ground.) Your car is not a reservoir for that kind of charge.

    The earth can handle a lightning strike without a (measurable) change in potential difference. This is why fish are not cooked in lightning storms.
