Should probably be something like "EU states that telemetry data collected from self-driving cars may be subject to copyright protection".
Then the bigger discussion should probably be - 'What is telemetry data?'.
If telemetry data is _any_ data collected from a car that could be remotely accessed, then in theory I'd argue that digital oil sensor readings, digital odometer readings and digital tyre pressure readings are all telemetry data if they are stored in a place that can be remotely read.
If that's the case - it could lead to the situation where car manufacturers demand (by law) that you are only allowed to service your car with them and not be a mechanic of your choice.
That may start as a small inconvenience that luxury car owners may be able to afford but as those features come to lower end models it may hurt average or less well off consumers.
Further more, what happened to 'facts' not being copyrightable (generally speaking).
