That would require a device with the power of an iPad. I’m sure it could be done but again adds another $500-$1000 to the final price of the car. A physical button costs a couple bucks. If we are going to get people on board with electric cars we need to get an economy version and any cost cutting they can do will make the difference.
First of all, an SoC comparable to an iPad isn't $1000 more expensive than what they're using.
More so, the current hardware they use is quite faster than the original 2010 iPad, yet the og iPad is dramatically more responsive than all these laggy cars.
Comparing Apples to oranges. The iPad ran so smooth because Apple spared no dev time expense in optimizing the SW to perfection using budgets of millions and devs with wages in the six figures plus.
Meanwhile automotive software is developed by the lowest paid and most crunched people in the industry, in line with the gaming industry, in bottom of the barrel, race to the bottom of cost cutting.
Especially that in Automotive you often have tons of legacy code that gets carried over because nobody wants to touch the old codebase, so all the crust keeps getting carried over, with new layers added on top because the device can't exist in a vacuum or in a tightly controlled ecosystem of the same manufacturer like the iPad, bust must be compatible to all the the other ECUs in the car developed by other companies and still be backwards compatible with the old platform.
Imagine having the iPad team operate at 10% of their budget and write their SW on top of Symbian OS, and be compatible with the Android ecosystem. Good luck getting a smooth experience there.
