Every manufacturer are creating their own proprietary systems so it is the wild wild west of the 'autonomous auto era'. The incremental creep of active-assistance driving will give way to total autonomous driving. For manufacturers it is NOT a real technology challenge but the 'herding' or standardization of these systems. The main reason are for LEGAL grounds. Congress and lawyers will have a boom. Traffic violations/insurance liabilities from all or any instances of tech failures, accidents and injuries/deaths in these vehicles. These have to be legislatively bullet-proof and fairly adjudicated before any large public acceptance. DOT AND FCC might be involved by requiring self-driving car-to-self-driving car standardized communications for safety and cooperative existence. Add to that traffic mix and complication of the last-hold-out real drivers and our 'off grid' old muscle cars. (they might still make it mandatory to have a smart device or smart phone, to identify our location & disposition in 'the system')

The last hurdle is the psychological jump by drivers/passengers to accept the ride of an autonomous vehicle.
