It's amazing to think that, in barely more than a decade, we've gone from the Keystone Cops to self-driving cars safely navigating the streets of many cities. A big part of that story is the amazing power of simply setting a clear goal and attaching a prize to it. I remember how graduate students and professors on the MIT team became so engrossed in the DARPA Grand Challenge, they forgot to eat and sleep. Humans can be incredibly dedicated and successful when we have a target in mind.
