Their decision to limit the initial problem domain is genius. When it comes to autonomous driving, safety is paramount. Limiting it to highways is a good way to ensure that you can maximize the system's safety and performance, while still getting a product to market that is ahead of the competition and which allows you to gather data and iterate to expand in the future.
SpaceX wants to go to Mars. Why haven't they yet? Do you consider them uninnovative? Or maybe they're just taking their time getting the technology right, because they know (1) they're leading the industry already, and (2) if they fuck it up, it would be a highly expensive mistake they probably wouldn't recover from.
