However, with both GPLv2 and GPLv3, a vendor of an aggregation of copyleft and proprietary software can legally cause the the proprietary software to stop working when the copyleft software is modified.

This would essentially brick your car/tractor until you rewrote that proprietary software from scratch. https://events19.linuxfoundation.org/wp-content/uploads/2017/11/Safely-Copylefted-Cars-Reexamining-GPLv3-Installation-Information-Requirements-ALS-Bradley-Kuhn-Behan-Webster-1.pdf https://events19.linuxfoundation.org/wp-content/uploads/2017...
