Swarms of teeny robo-tractors will outmaneuver Tesla’s driverless cars
Between 2009 and 2015, Google spent $1.1 billion on autonomous vehicles for its Waymo subsidiary, which have so far roamed more than 10 million miles of city streets — though none of those miles have yet involved a paying customer. Tesla, which builds the data collection it uses to improve its autonomous technology into every vehicle it sells, lost more than $1 billion as a company last year alone. In pursuit of viable self-driving cars, the companies have had to navigate a web of regulation that varies from state to state, apply for permits, and risk getting banned from roads if they fail to follow the rules. Neither of their self-driving technologies is ready to be set loose on public streets without a human safety driver behind the wheel or navigating previously approved routes.
