Just like Ericsson and Nokia? They didn't stand a chance, as history has proven. Especially given most of these car companies don't have a huge pile of cash on the sidelines.
Social-signalling/being a 'high-end' phone is what the iPhone's success rode on, and there were no high-end smartphones (well, there was Virtu but they were more botique than mass-produced high-end).
There already exist a smorgasbord of luxury cars that are social signallers; Apple will have to do something much more 'revolutionary' than they did with the iPhone. There weren't any smartphone equivalents of Mercedes-Benz, Porsche[1] or Maserati.
But Apple is still perceived as a premium brand by many. I am unsure of how many of those belong to the class of people who will buy a premium car but am willing to bet there are just enough to be dangerous.
Apple is also more well-known than Tesla currently. I still think it won't be easy for Apple but I've learned to appreciate the power of market perception.
