I'm pretty interested in this too. I've thought about it in the past, and I think get stuck where you're asking (the post processing and visualizing bit).

I'd thought of having GitHub actions for the measurement, stashing the results as artifacts, then having another workflow that processes the results. Obviously pretty DIY so I'm curious if others have solutions.

As much as I don't want Tesla to hold a monopoly, I think this change does help with being able to drive out to more remote locations, like national parks in the US.
