The IRS provides a list of free filing websites: https://apps.irs.gov/app/freeFile/browse-all-offers/
I believe they may even pay these companies to offer the service.
Free Tax USA doesn't have an income limit, and may be the only one, so I've used them for at least 5 years. They charge $10 for state filing, so I use CalFile instead.
My tax situation is pretty simple and they've filled my needs. The only issue I've had is with exempting Treasury bills from state tax but I don't file state with them anyway so maybe I missed something.
I believe I've heard the newer Mazda 3s have added the navigation into the HUD for Android Auto and Carplay. It's not in my 2020 though which is annoying.
As for selling your data, yes absolutely. It goes to Connected Analytic Services which is an affiliate company of Toyota Insurance. Toyota Insurance Management Solutions (TIMS) is another name to look up. Subaru sells your data to them as well.
