As, per John Markoff of The
New York Times, “in and around Silicon Valley, at least 19 commercial
self-driving efforts are underway,” the topic of driverless vehicles continues
to set publication proliferation records among jobs-related subjects. I am looking at a stack of 29 articles from
no fewer than 12 different publications, all within the past 73 days. I won’t try to review all of them, which
would be a waste of space for several reasons, but will summarize what has
happened here, sorted into four major themes, since word of the first fatal self-driving
mishap broke on June 30.
This crash took place May 7th in Williston,
Florida, when a Tesla driver activated the car’s Autopilot feature, completely
ignored what was happening on the road, and then died when his vehicle ran full
speed into the side of an 18-wheel truck.
After almost three months of investigations (we’ll need to get faster
here), and initially saying that the accident happened because the product did
not correctly interpret “the white side of the tractor-trailer against a
brightly lit sky,” the Tesla company determined that the problem was not that Autopilot
failed to perceive that there was a large metal mass straight ahead, but that
its braking system did not then stop the car.
In the meantime, Consumer Reports
implored the company to block use of this feature while the drivers’ hands were
off the wheel.
A few observations here.
Apparently Autopilot, as well as being named aggressively enough to
encourage drivers to, in the findings of another article, play Jenga, watch
Harry Potter, and actually sleep, is in fact a beta release, meaning that it
has not been fully tested. If the
linkage between its autonomous driving capability and its brakes is insufficient,
it is in effect little more than cruise control, around since at least the
1960s and nothing any prudent driver would ever trust with full vehicle
operation. It is not, as I defined the
levels in my July 1 post, a true Plane 2 feature, as drivers cannot disengage
while it is operating. Whether the
actions above were reckless, appropriate given the name of the feature, or
somewhere in between, and even though the cars’ manuals gave warnings, it is
clear that Tesla dropped the ball here.
They will probably lose large lawsuits over the product, and will be
required to back it off in some ways.
The broader ongoing issue will be to avoid excessively slowing down availability
of automated driving products. There
will be more mishaps – in fact, on July 1 another Tesla crashed, rolling over
on the Pennsylvania Turnpike without fatal injuries – and their liability here
does not mean the maximum acceptable rate of accidents should be zero.
The second subtopic here is about company alliances and
consortiums, which I predicted July 1 would ultimately produce these vehicles. Later that same date, German automaker BMS
AG, American chipmaker Intel, and self-driving Israeli software company
Mobileye NV announced that they, together, expected to be producing
self-driving cars of some autonomy level by 2021. About three weeks ago, American ridesharing
company Uber and Swedish car manufacturer Volvo announced combining to offer automated
taxis, which will be on Pittsburgh roads this fall. In good deference to their necessarily
incomplete quality, they will be free, and at Plane 2 or Plane 3 (a driver
still inside, but rarely taking the controls).
How this aggressive and possibly premature but fascinating experiment
works, or fails, will tell us a lot about what we need to stay on my projected track
of 20% Plane 2 United States vehicles by 2021 and 20% Plane 3 ones by
2025. Uber has also acquired American driverless
truck technology maker Otto, which gives it two consortium pieces on that front
in-house. Ford, now with potent
production plans of its own, is working with Israeli computer-vision company
Saips, has bought 75% of American lidar (radar based on laser beams – expect to
see this term more and more) sensor manufacturer Velodyne, and put undisclosed
amounts of money into American digital chart firm Civil Maps and American machine-vision
concern Nirenberg Neuroscience.
The third theme concerns announced
availability dates for various vehicle automation products. A July 4 article said that Google “hopes” to
market what might be called self-driving bumper cars, with 25-mile-per-hour
maximums, “a heavy later of foam” on their fronts, and plastic windshields, in
2019. Those would go all the way to
Plane 5, or vehicles without direct human control; although I projected they would
not reach 20% of American rolling stock until 2030, we could still reasonably
have 0.1% in three years. General Motors
now plans on a 2017 offering of Super Cruise, an apparent Tesla Autopilot competitor,
designed as a true Plane 2 product but functional only on highways which the
company has mapped in detail. Ford
announced on August 16th offering large numbers of fully driverless
cars, at Plane 5 or at least Plane 4 (remote human supervision of vehicles or
groups of vehicles; my prediction 20% in USA by 2028), through a ridesharing
company to be named by 2021. And in four
miles of Singapore streets, American company nuTonomy has zoomed ahead of Uber
and Volvo by offering free experimental semi-driverless taxi service now.
The fourth article concentration
is on other updates to issues I raised in my November 20th
post. A July 7th piece
proposed that, like 16-year-old humans, new driverless technology pieces should
be licensed – a sensible idea, especially if the turnaround time is much
shorter than those government often perpetrates. A second, on July 8th, reinforced
the special need for road and other infrastructure improvement. A third, also out July 7th, again
raised the behavior issue, with Plane 2 drivers averaging 17 seconds, or a
quarter of a mile at only 53 MPH, to retake control after the vehicle’s command
to do so. An August 18th
article addressed one I haven’t seen since bringing it up in November, the
threat of hacking, with a graphic example of a researcher stopping a
self-driving car by issuing commands on his laptop.
As far as jobs go, my July
projections on those, as with the percentage implementation dates, are still
current. Uber seems to be insisting that
driverless vehicles will slash the number of privately owned cars, which seems unlikely
in small towns and low-density suburbs and absurd in rural areas. I’m still expecting 20% of American vehicles
at Plane 2 by 2021, privately owned or not, with the world’s self-driving
leaders there by 2018. And eventually
our terminology will change. Per Ben
Zimmer on August 26th, we may come to know of self-driving cars as
just “cars,” and the ones we have now as… “meatmobiles.” I leave it to you to propose other names for
what were once known as “horseless carriages” – in the meantime, enjoy watching
the progress of what might, arguably of course, be the most exciting, and most
promising, area of technical growth we have seen since Apollo.
