Can't wait. Think about it: 20 years has been the average development span for auto tech - manual, automatic, comfort, speed. Simple search: automobile 1900 to 1920 - check out the leaps in tech.
Twenty years from now all public transit will be robot driven. Subways, trains, buses. Drivers, conductors will be customer service, safety folks.
Twenty years from now all personal vehicles will be electric/or electric hybrid. i.e. purring away charging.
No oil changes, gear boxes, no fluids. No maintainence, no mechanics. Swap out components.
Insurance. Auto drive sure. Manual intervention heavily penalized. Realtime monitoring will assure lower rates. Mostly drives will be driverless. Certain service vehicles: cabs, trucks, point to point shipments will be entirely automated.
Silly rude cabbies: UBER is not the the threat to drivers - it's the tech that will eliminate the need for drivers. Shields/licenses will ensure owners can run a cab provided they are driverless. One just has to survive the transition.
Semi auto vehicles won't be allowed on "premium roads" unless certified driverless. Premium roads: DVP, 401. Either you give your vehicle to road control or you won't be permitted. No speeding. No matter. Everyone travels at 150K. Low fuel, malfunction, you exit.
Initially, the might be a toll for non-driverless vehicles and they will be restricted to slow lanes so can you watch the driverless, wiz by at premium speeds bumper to bumper.
And then you notice: "Wait. Was that dude actually fuckin' her? I gotta go "drive her ass"
