Does your phone connect to mobile network? If so, your network provider knows your location at all times, because they need to triangulate your position via the network to make sure your phone ends up in the right cell. And yes, they do save your location history, and if you are in a country like the US, you gave them the rights to sell that data when you signed your phone plan.

Do you use SMS messages? They are unencrypted and the contents are saved too.

Do you use DNS? Yeah, also unencrypted, and yeah, also that is saved and tracked, no matter which DNS server you configured.

All of this is way more critical information about you than the car tracking whether you are awake or not.
