Apple CarPlay “Ultra” will never gain a foothold. Maybe with no-name manufacturers, but not with well-known brands. You can forget it.
Because what is the basic premise?
Apple says: “We get the vehicle data, we have access to all systems, and everything looks exactly the way we want it to – but you, the manufacturer, are responsible for the vehicle and all problems.”
Now think about it: as a manufacturer would you want to do that?
Be the scapegoat for everything while another company reaps the rewards and collects all the data?
It was clear from the start that CarPlay Ultra was a stillborn product. No major manufacturer would give Apple full access without getting something in return.
