Regulators scramble to stay ahead of self-driving cars

Self-driving cars are only starting to navigate the nation's streets, but regulators are scrambling to catch up. In the race to deliver cars that can safely operate themselves, proponents are increasingly concerned about a fast-growing thicket of regulations and laws being proposed by states that could come in conflict with each other and threaten to hold up development. "It could be messier, and it could take longer than we want it to," IHS Automotive analyst Stephanie Brinley says. "We will see some state-by-state and some federal fights happening." Some believe the federal government must step in to create a national standard pertaining to testing, crash liability and design requirements.
