Great write up and cool piece of kit. Your idea about not wiring it directly to the battery is a good one, but I think the kind of thieves that go after luxury vehicles tend to immediately disconnect the battery. Would be great to have a tiny auxiliary battery inline that could last 24 hours without the main battery.

The best part of this is that you're giving a company access to every place you have every gone, how you got there, and the speed you travel at. Thank god no corporation has ever been manipulated to release private data.

Cheers!
