You make the mistake of thinking Apple cares about market share. Their philosophy has always been to take the largest share of profit [1], with their phone market share hovering around 10% depending on country. Similarly their computer market share hovers around 5%, but it remains highly profitable.

Pair automation with a small, likely stylish car and demand from city-dwellers would be enough if Apple released something compelling.
