If I have a towing tool for your car, be sure I have a Faraday cage too to block all your GPS trackers while I dismantle the car. Think big truck that is isolated from both sound and electromagnetism and I simply hack at your car with my wrenches, selling your expensive Tesla for parts.
GPS jammers are less than $30 on Alibaba, truck drivers have been using them for over 10 years [1] to defeat their bosses tracking devices.
Multi-Band Jammers are $1000, burglary rings are using those to block all Wi-Fi, cell, GPS signals - check out this arrest report from last week in Pennsylvania [2]. If I was a high-end car thief, like in Gone in 60 Seconds, that's what I would use.
I think you missed the point. The Faraday cage is built inside the truck's cargo, and I put the car inside the Faraday cage directly. I also dismantle the car while the truck is moving so when I reach the chop-shop the GPS and all the car's guts are ready for sale.
