Wireless implies batteries. Hell no.
IIRC one of the issues with the 737 Max was that it had wireless internal components whose lithium ion batteries could catch fire. If you can't even get batteries right on a product constantly maintained by a professional crew, what are the odds of it working out well in a car?
If it's BLE, it could last years on a coincell battery. I don't find that to be a problem if it can give a warning in advance of running out.
