Their team is focused on figuring out how to build a car for at least the next few years it seems. Tesla already knows how to build a car and so their engineering team is already looking at the next thing.
It's not like Apple can throw unlimited cash at the project. They have shareholders to answer to so they still do have to be mindful of the budget.
Your opinions are based on nothing more than the fact that you think Teslas are cool, and not on any facts or logic.
Tesla vehicles are the lowest quality crap on 4 wheels since the Yugo. It is impossible to look at any Tesla, and not spot uneven panel gaps, leather stitching coming apart, orange peel paint or ripples, and that's just the cosmetic stuff.
Parts flying off a car are unheard off with other brands, but with Tesla the rate at which roof panels, bumpers, and other parts fall off is comical. Multiple recalls have been issued for things like roofs coming off due to poor quality adhesives or forgetting to use the correct primer, loose steering components due to corroding bolts, and improperly routed battery cables that resulted in fires. All of these defects have one thing in common, poor quality control and manufacturing processes.
Also, there isn't anything uniquely special about them with respect to automation or in-car technology. Tesla is particularly good at battery and motor technology. That's it. But even that isn't a huge competitive advantage, as Porsche and even Ford are now producing electric vehicles with similar (though not as good) efficiency. It won't be long before these better-funded competitions (who don't have the QC problems Tesla has) catch up and even surpass Tesla.
And you are wrong. Apple
can throw stupid amounts of money at the project, assuming it even exists. Apple spent $16 billion in R&D in 2019, and is forecast to spend $20 billion in 2020. Tesla,
during its entire existence, has spent around $7 billion---about what Apple spends in 4
months.
You are also wrong that Apple has "shareholders to answer to" with respect to R&D spending. Shareholders have
zero say in R&D spending, and Tim Cook does not need shareholder approval to allocate funds to R&D.
Even if he did need approval from someone (more likely the board), it is absurd to think that they would basically say, "Sorry Tim, can't afford it." Apple could spend
triple what Tesla has spent in the last 10 years, and still have
$175 billion in cash left over.
