Am I wrong in thinking another potential low tech solution might be to just remove the cellular radio? To be clear, I'm asking more than anything as I have very little car knowledge but to me that seems like a more preferable solution long term than frequently having to physically disconnect your car battery.

Yeah, probably a viable solution to just disconnect its cellular antenna (though it could easily be a PCB antenna, in which case... x-acto knife I guess)

  How will that help the issue that the module keeps waking up and trying to send data until it succeeds?

    The primary reason why it is an issue is because it causes the cellular antenna to constantly draw power from the battery. So my thought was "Why not simply remove the component physically drawing all that power and just call it a day?"

  Depending on what kind of protection they have in place, that may kill the electronics. You may not care if it’s a separate cellular device, but will if it’s part of the head unit. Your best bet if you actually want to do this would be replacing the antenna with a properly matched dummy load. But that (or removing the antenna at all) is going to just leave you with exactly the problem you already have—it can’t make a connection, so it will continue retrying (and probably at its highest power setting) forever and drain your battery.

The majority of the power being drawn occurs because the system mistakenly believes the band is still usable and assumes that it probably just located somewhere with poor reception. This causes the system to ask the radio to bump up its radio power and when that doesn't work, wait x amount of time and then try again. However by stripping the cellular antenna, we make it impossible for the system from executing that behavior. Sure it'd periodically wake up and inevitably fail to initiate a scan but that consume vastly less power. (to the point that it'd likely be a non-issue)
