As car makers begin to invest heavily in self-driving vehicles, new questions and concerns are beginning to emerge about who will gather data on these connected cars and their potential for privacy violations.
2014/10/21: The autonomous Google car may never actually happen.
Google admitted to me that the process it currently uses to make the maps are too inefficient to work in the country as a whole.
To create them, a dedicated vehicle outfitted with a bank of sensors first makes repeated passes scanning the roadway to be mapped. The data is then downloaded, with every square foot of the landscape pored over by both humans and computers to make sure that all-important real-world objects have been captured. This complete map gets loaded into the car’s memory before a journey, and because it knows from the map about the location of many stationary objects, its computer—essentially a generic PC running Ubuntu Linux—can devote more of its energies to tracking moving objects, like other cars.
But the maps have problems, starting with the fact that the car can’t travel a single inch without one. Since maps are one of the engineering foundations of the Google car, before the company’s vision for ubiquitous self-driving cars can be realized, all 4 million miles of U.S. public roads will be need to be mapped, plus driveways, off-road trails, and everywhere else you’d ever want to take the car. So far, only a few thousand miles of road have gotten the treatment, most of them around the company’s headquarters in Mountain View, California. The company frequently says that its car has driven more than 700,000 miles safely, but those are the same few thousand mapped miles, driven over and over again.
Another problem with maps is that once you make them, you have to keep them up to date, a challenge Google says it hasn’t yet started working on.
I have an excellent job at a great university. I have a home that I love in a community I've lived in for two decades where I have deep ties of family and friendship. Unfortunately, that university and that hometown are about 250 kilometers from one another. And so, I've become an extreme commuter, traveling three or four hours each way once or twice a week so I can spend time with my students 3-4 days a week and with my wife and young son the rest of the time.
