My city, Hamilton,
just started testing driverless cars on the Mountain. They're manned at the moment, but it may just be a matter of time before they are unmanned like some fleets in some USA cities.
Stretch out the timelines from 5 years to 10/20/30 years and what's happening is going to pretty much happen. I don't think it'll happen as quickly as the graphs suggest throughout the whole country. The first city may follow the trends in this YouTube in a mere 5 years (perhaps a sunny Arizona city), it will take much, much longer in most parts of Canada.
Five years later, this is what I expect:
"Look, all these predictions were true!" -- in some cities
"Look, all these predictions were wrong!" -- in other cities
Even though we're already doing a lot of TaaS (Transport As A Service) today.
The selfdriving will take a while to become safe in winter weather here.
-- We tap our Presto-like cards on a spare carshare car and drive it away on the spot (Autoshare, Zipcar, Vrtucar, etc). Unattended rental.
-- We press a button on a pocket computer called a "smartphone" to magically bring us a Uber.
-- Tomorrow, all of these will be unmanned self-driving cars
The new generations doesn't feel the convenience of owning a car like the 20th century teenager pleading for a driver license at Sweet Sixteen. The are pleading for smartphones rather than cars. And they'd rather fondle a smartphone in the backseat of a Uber (or as standee on a New Streetcar). Even an increasing percentage of the Older Generation too. The magic of car ownership isn't as alluring as it used to be, even as I own a car myself too...
I think it is only a matter of time that the driverlessness collides with Ubers & carshare, to make it deliciously more tempting than owning a car. A clean robomaid-serviced car|truck|etc arrives to you, and handles your heavy duty mobility needs more intense than subways, bikes & ridehails. But the driverless stuff is easy in Arizonia, but devilishly hard in Ontario blizzards. So major TaaS disruption may arrive in some cities before others.
Convenience & economic forces will trend towards this. The high cost of self-driving cars and the convenience of carsharing / apphail / etc. For example, even puke becomes a solved problem: The future selfdriving car has cameras that catch the issue & drives the car to a maid service for cleaning & autocharges the last user for the cleaning cost.
One big problem is there's also dystopia scenarios too -- number of cars don't go down, roads/parking still expands, and everybody sends their empty cars away (clogging freeways) to soccermom far-away kids around. THAT is scary and very environmentally unfriendly -- and we'll still need all the parking too.
