How are we groping along with what we expected, five years ago, to now be widespread?
The partially autonomous version, per “11 more crash deaths
are linked to automated-tech vehicles” (Fox Business, October 18th)
has issues of its own. While it’s not as
bad as it sounds, for “mid-May through September,” and is not really “alarming”
– we don’t hear about how many fatalities come from, say, faulty tires – it’s
still getting attention. Ten of these deaths
involved Teslas, of which there are 830,000 in the United States with this
technology. But driver errors still kill
over 40,000 Americans annually.
One application having real if small-scale autonomous
success is taxicabs. In the November 1st
Emerging Tech Brew, Hayden Field looked at how it might continue growing
in “Why some robotaxi companies are looking for their Goldilocks cities.” Waymo, the implementation leader, has decided
to focus on “scaling up an individual city rather than trying to be in 15”
simultaneously. When the company wanted
to operate in “a city that was semi-challenging but not impossible,” Phoenix
offered “medium-high speed limits across many roads; a friendly regulatory
environment; a fast-growing population; challenging maneuvers like unprotected
left turns across three lanes of traffic; neighborhoods with varying population
density;” and no snow or ice on roads.
Next up is San Francisco, where similar efforts have been tried, valued
for technical proximity and compactness.
The piece also mentions a potential financial hurdle, as cities not
wanting excessive numbers of empty robotaxis driving around might levy a
“zombie tax” on them.
Soon thereafter, we got bad news from there, in “Self-Driving
Taxis Are Causing All Kinds of Trouble in San Francisco” (David Zipper, Future
Tense, December 8th).
They had a 140-passenger trolley stopped as an autonomous vehicle
“halted on the streetcar tracks and wouldn’t budge,” though human intervention
held the delay to seven minutes. Such
cars also have “blocked a travel lane needed by a siren-blaring fire engine”
headed for a three-alarm blaze, and “dozens” of them “drove daily into a quiet
cul-de-sac before turning around, much to the frustration of nearby
residents.” Accordingly, people there
and elsewhere “should brace for strange, disruptive, and dangerous happenings
on their streets.”
Reporters have told us before what it is like to take rides
in autonomous vehicles, so how different was the latest, from Cade Metz et al.
in the November 14th New York Times, as they told us “What
Riding in a Self-Driving Tesla Tells Us About the Future of Autonomy”? This six-hour ride was in Jacksonville,
Florida, not a hub of self-driving activity.
The story, which with pictures printed out to 14 pages, showed a mixed
bag, with “more than 40 unprotected left-hand turns against oncoming traffic,”
ability to change lanes and recognize green lights, and general success at dealing
with “highways, exit ramps, city streets, roundabouts, bridges and parking
lots,” but also, when going to a restaurant, “veering from the road into a
motel parking lot,” almost “hitting a parked car after we rolled over a low
curb,” and a need for the test driver to retake control “every so often” as the
vehicle “makes a mistake.” The authors
concluded that this “Tesla Model Y provides a glimpse of the future we are
moving toward, which may prove to be safer, more reliable and less stressful,
but it still years away from reality.” “Experts,” they maintained, “say no
system could possibly have the sophistication needed to handle every possible
scenario on any road,” as “this would require technology that mimics human
reasoning – technology that we humans do not yet know how to build.” This conclusion seems after-the-fact, as it
was not present in the great expectations of 2017 – we don’t know if it is true
or not, and if so, how long it would take to create it.
After returning from a family driving vacation, Ross Douthat
held forth on “What Driving Means for America,” in the July 20th New
York Times. He invoked a Matthew
Crawford book, Why We Drive: Toward a
Philosophy of the Open Road, in which the author backed “the human being
who moves purposively through the world rather than simply being carried
through it,” and advocated being “mentally involved in our own navigation and
locomotion.” Douthat considered driving
a way “to a nonvirtual experience of the America beyond your class and tribe
and bubble,” but admitted there might be other means to that end. We could relate experiences of airline
passengers, who go from airport to plane to possibly very distant airport just
as passively. It is certainly a
tradeoff, but seems like a problem more comparable to that of choosing only
more entertainment instead of fdgconstructive and self-directed pursuits. We won’t solve either one soon, but
driverless cars, to the extent that we can get them effective and common, can
offer us a great deal, and should not be precluded or rejected. On that we need to aim.
