People feel that cars haven't really improved much in practical terms over the last 20 years. At least to the layman, they don't feel smoother, safer, more comfortable to drive. They just got more expensive, more cameras and crap like auto-start that no one asked for.
So at least the hope is to take some of the best parts of modern software manufacturing and apply it to the car. Tesla did this and is why it was the first successful car company that's been started in the past 50 years or so.
