Where you go can not be inferred from the charging sessions. You can kinda infer the speed, by looking at the state of charger between two sessions. You can't infer with whom you're travelling.
Honestly, people always overinflate the usefulness of "data".
Ford will track your entire drive, how you used your car, even the radio station that was playing. All of this data is uploaded when you take your car in for servicing if you do not have a connected car.
OnStar recently (2-3 years ago now?) started feeding 100gbps of telematics data on every single GM car back to GM in an effort to determine better pricing on used cars. Data includes every sensor change on the car and even details from the onboard wireless entertainment system (your wifi device)
These are projects I have worked on. They have an overabundance of data on you and 99% of you fit the model of usefulness
We're telling you this is a multibillion dollar business that's transforming the world around you. You may choose to ignore or downplay it, but it won't change the facts. Even If you're paying for something you may not be the primary customer anymore since there's more money to be made from tracking you than from selling you stuff.
Also, Ford and GM do not do service. A lot of the detailed car information can really help with service and maintenance. But dealers actually don't want that to improve systematically and Ford doesn't gain enough from it.
Tesla makes all that dealer profit themselves and can systematically improve service and make a huge profit from off warranty vehicles. This is a huge revenue stream Tesla is only just starting to get. Something people often miss when they look at future profitability.
Ford and GM make huge amounts of money from part supply fro off warranty cars. Tesla will do even better because they will do the service, not just the parts.
