Previously, I wondered what model car I should buy if I wanted to maintain my privacy. Thanks to everyone who chimed in, especially @kari, @qot, and @Narry. Although I astound myself to be typing this, I may just have found an option in a Cadillac Lyriq.

Earlier this year, the FTC banned GM from selling driver data to consumer reporting agencies and GM ended their egregious program. This and privacy laws in my state give me some small hope of avoiding the worst data collection practices. But, if I buy this car, I would want greater certainly that can only be had by physical intervention. Local audio/security aftermarket installers have nothing for me. Would anyone have a resource or ideas?

Angry Scott Morrison accuses GM of letting Holden 'wither away' after taking $2bn in subsidies

For context: Holden is an Australian home-grown brand. It became a subsidiary of General Motors in 1931, but it started manufacturing cars in Australia from 1948. The 1950s FJ Holden is an Australian icon. The Holden Commodore was the family sedan for Aussies all through the 1980s & 1990s. Aussie car lovers fell into two tribes: Holden or Ford. If you ask any Aussie to name a few famous Australian brands, Holden will get a mention.

General Motors stopped manufacturing Holdens in Australia a few years ago, but they assured us that Holdens would continue to be made (albeit overseas) and sold here.

Now the brand itself is being axed, at the end of next year.
