That may be the case, but that hasn't prevented Tesla from not including CarPlay in its cars. But, unfortunately for GM, GM is not Tesla when it comes to EV market dominance and can ill afford such stunts.
Tesla is probably on borrowed time in this respect.
They have been able to succeed based on the combination of
- people wanted electric (for various different reasons)
- their UI was good enough
- the charging network is great and easy/convenient to use (along with home charging)
But as the charging network seems to moving towards cross-brand functionality (one step, one law, at a time, but that's where we're headed) and as other brands provide nice electrics WITH Car Play this will start to play out rather differently.
I know for example one female friend who has zero strong opinions on tech (car or phone), she just knows that she likes CarPlay's navigation much more than anything else. Combination of
- the voice sounds more realistic [Tesla is very harsh, Google somewhat harsher]
- Siri doesn't speak too often [Google is far too chatty]
- Siri speaks at just the right time in advance, and with good explanations [ie go through this light then turn left at the next light, not "turn left in 800 yards"]
This matters to her enough that I set up her Tesla so that she gets Apple Maps/Siri navigation by bluetooth audio, and uses that all that time, in preference to native Tesla navigation...
