Given the great leap that autonomous and semi-autonomous technology represents, and the interesting questions of where liability will fall should an accident occur, California's approach is understandable. It is also easy to understand the frustration of developers and manufactures who want to progress this technology as quickly as possible, particularly given the possible rewards of winning the race. However, I would expect California's approach to be common as this technology progresses, at least throughout these early stages. Public acceptance will most likely be a slow and steady process, and I would expect regulators to follow suit.
