I dont think the world is ready por driverless cars. Especially in countries of South America, Mexico DF, India where transit is almost impossible for human minds even less for AI. It will require too much artificial intelligence to consider in seconds the best result before crashing or running over a person before an animal, in the worst case scenario.
DAV, for what I read gives me the impression that It is an Uber without the Uber, that is, without the intermediary. It is a very interesting project to bring blockchain technology to the world of transportation, either for transporting loads, shipping, or simply bring a person from one site to another. From this point of view, it can be used for many activities and businesses of transportation.
The idea behind DAV is that it provides the technology to decentralize exchange of any transport service. The biggest use case would be, as you said, to make a decentralized Uber. And yes, it'll be interesting to see how it folds.
Haha I like how you describe the difficulty of driving in some countries in such an eloquent way.
