Infotainment responsiveness needs to be a NHTSA regulation. The mental load of dealing with laggy and unresponsive radios is surely causing accidents. Even if at worst it adds another $100 to the cost of the car to get a good enough cpu, so what?

Apple made a computer with a fast, responsive UI in 1984 using a chip that ran at 7.8 mhz and had 128 kb of ram.

You don't need a fast chip to eliminate lag. It's just incompetence.

Sure. I've used home computers since 1979. The graphics were instantaneous back then even on a few MHz and 16 kBytes of RAM.

We don't want slow and laggy UIs because the software is bloated.

But I responded to this part:

And my point was that it is far harder than it seems to put more powerful CPUs in cars.

They weren't doing that much either. I doubt an Apple ][ could even stream modern audio codecs via bluetooth, let alone simultaneously run a local search on the GPS database.
