...Which is why this thing will never happen in Australia first.
In 2 years, early adopters will be in driverless cars. By 5 years, all new cars will be electric, driverless with the ability to be put to work generating the owner money. Cars will switch from ownership to car-as-a-service. The transition will be households with 1 car instead of two, and primary commuting done driverless.
By 10 years, about when we're landing people on mars (and doing return journeys every 2 years when Earth & Mars line up), countries will mandate zero cars be internal combustion engine. 100% of new cars sold, with perhaps some exceptions for vintage models, will be electric driverless.
Now back to our drone thing: how hard do you think it will be for regulators and rule makers to see an autonomous drone concept as safe in 5-10 years. Incredibly easy. Considering aviation automation is much easier than cars. And the same regulators will probably be catching a ride to work where their car drives them.
Don't compare an R22 with this concept. Autonomous drones will have 4 to 12 electric motors. Incredibly simple and fault tolerant. Ballistic parachute most likely.
But it won't be Uber that does it!
