It's understandable though that Apple might prefer customers not to use Google services as they are direct competitors. But car manufacturers do not compete on

It's understandable though that Apple might prefer customers not to use Google services as they are direct competitors. But car manufacturers do not compete on the "digital maps" market (nor are they direct competitors to Apple or Google... yet), so I really don't get why they'd prefer to reinvent the wheel. Independance is one thing, but as a customer, as you said, I want the best experience for me, not the manufacturer.
