What about variably-autonomous cars? Take a car with self-driving capability and then have it be manually operated while solitary but increasingly self-driving as the group of similarly automated cars it belongs to grows. There&#x27;s a lot of benefits to group awareness: share sensors, coordinate behavior for efficiency, instant communication, and so on.<p>This gives us the best of both worlds: safety in numbers, safety in automation and sensors, and it retains the personal autonomy we&#x27;re used to. All while not requiring 100% perfect autonomous capability.<p>If the cars were small and cheap enough, they could be made available via subscription (much like a lease) and treated like a municipal transportation network that&#x27;s superior to light rail and bus networks.
