Incumbent car manufacturers are actually lightyears behind in experience that Tesla provides. Just look at their dealership model that is design to robe user at every step in the process. From tech perspective, majority of Toyota line up still doesn't even have good smartphone connection story in 2019. Honda still have bare minimum driver-assist. Toyota Sequoia hasn't been literally updated for years and a giant car like this doesn't have basic safety features that one would expect in 2019. Keep in mind these are the biggest, wealthiest and most powerful car manufacturers in the world for who money in not an issue. They have perhaps 10X more people working on improving designs than Tesla but at the end of year nothing really comes out. If you look at model differences between 2018 vs 2019 for large majority of incumbent manufacturers, you will see no difference or something tragically trivial such as offering new shade of color. You may think what the hell their design staff of thousands of people did this entire year?

Tesla's main strength is design, courage and agility. Everything from door handles to dashboard is made to delight the user. They are tech company that became car company, they move fast and they deeply care about delighting users. Ideas don't boggle down in bureaucracy. Model-3 is upgraded even before year was over. Model-3 is designed for million mile life. No incumbent manufacturer would dare go in this territory. The difference is same as incumbent software giant vs new startup.
