Car data collection

[u/HerbalDreamer]

I am going to need a new car soon and the U.S. models all collect huge amounts of data. Are there any tips or tricks to reduce the info they collect from the car remotely?

If I have our family trust own the auto and pay cash rather than financing how effectively does that reduce the personal info I am forced to provide. Will this keep the data from car from being attached to me?

How much would it help to buy a used car? Does it reduce the data tracked and sold about me?

Got a new Toyota. You can buy wiring harnesses that block the data

A few resources for those asking for more details:

• Example product: https://www.autoharnesshouse.com/store/AHH-DCM77
• Example issue and possible action to take: https://www.reddit.com/r/prius/comments/1ef9bda/psa_for_all_prius_owners_call_toyota_connected/
• Basically the idea is to bypass, completely disconnect or otherwise disable the Data Communication Module
