worth to remember: There's a jokey truism in software development that the first 90% of the problem takes 90% of the time, and then the last 10% of the problem takes 90% of the time. Autonomous driving is like the fractal version of that. Every last 10% takes 90% of the time, and every last 10% of that 10% also takes 90% of the time.
