Let's not forget that when the Karma was being spec'd out in 2007-2008, the Ipad was still two years away from being unveiled and the Iphone 1 had just come out, and the touchscreen-only control system was never used in any car before that. To this day, a lot of very expensive car's control system rely on joysticks rather than screen touch to communicate with the software. The lead time for this kind of technology is pretty long and the complexity of the real-time systems in a car require a different approach than a tablet that can freeze without anyone getting killed.I liked the iPad comment - though surely he forgot about the Model S.
My 2006 VW GLI had a touch screen as well. Loved it.I purchased revised Porsche Cayenne Turbo more than two years ago and their touch display works without any problems. Ipad music interface is by far superior to what is in Fisker Karma. I believe such touch display was in Panamera even longer than 2 years. Plenty of time to get inspired. So I am afraid I am not so generous with slack as Fabulist.
I think that's a valid statement if you are an existing OEM with many sources of revenue. Maybe not so much if it is your first product plagued with delays & limited resources.
