‘Software, Start Your Engines’
The 2021 Indy Autonomous Challenge is a high-speed laboratory for
advancing automated driving.
Ensuring clean and safe cabin air and contact
surfaces in AVs is now a top priority for
vehicle developers. Tier-1 supplier Gentex
Corp. is actively addressing it with its
portfolio of sensors (including smoke
detector technologies), microelectronics and
connectivity-focused products. (Gentex)

Fool Self-Driving
I think we all get a little fatigued
with the almost daily barrage of Tesla
news. But even by the company’s and
the media’s standard for hyping all
things Tesla, the mid-October “beta”
release of Full Self-Driving software
for Tesla’s controversial Autopilot
automated-driving system stoked the
flames to new heights. Why? Because
Full Self-Driving really isn’t close to
its billing.
From startups to OEMs, the
industry has spent years walking back
initial technical over-promise and
brazenly optimistic production time-
lines for high-level automation. This
while many auto- and tech-sector
veterans continue to misinterpret, or
willfully ignore, the specific defini-
tions of SAE International’s universally
acknowledged six-levels of driving
automation. So little wonder when the
world’s most closely-watched auto-
maker launched a software upgrade
called “Full Self-Driving,” chaos ensued.
Mr. Musk is running a business and
has a right to make whatever claims he
wishes for his product — up to a point.
But where that right stops and protecting
public health begins is the crux of the
long-running dialogue about how
much regulation should be attached to
autonomous-vehicle (AV) development
on public roads — and who should be
doing that regulating. Tesla believes in its
own standard, apparently: FSD’s written
cautions include an admonishment that
the driver must always be attentive and
hands must always be on the steering
wheel. And that the system “may do the
wrong thing at the worst time.” With a
straight corporate face, the company
proclaimed it released the FSD software
exclusively to an initial group of “expert,
careful drivers.”
Wait, what?
That seems to be the position of
many industry sources — but strangely,
not necessarily that of regulatory
bodies. The Partners for Automated
Vehicle Education (PAVE, of which SAE
is a member) wasted no time calling
out Tesla’s nonchalance. It described
using untrained consumers to validate
beta-level software on public roads as
“dangerous and inconsistent with existing
guidance and industry norms.”
The National Highway Traffic
Safety Administration public state-
ment on this matter was illuminating
in calling FSD for what it is: “an expan-
sion of its [Tesla’s] existing driver-assis-
tance system.” NHTSA will monitor the
new technology closely and pledged
to “take action” to protect the public
against any potential risks to safety.
As the FSD situation plays out, I
wonder about the ramifications for near-
term development of high-level auto-
mated driving — and whether any of this
is positive for consumers. Just weeks
before Tesla’s announcement, Waymo
confirmed it was prepping to get back
in the robo-taxi business, expanding
driverless rides in Phoenix beyond its
original Waymo One subscriber-based
service that was suspended at the
onset of the COVID pandemic. Waymo
also bandies the term “self-driving”
and there’s fine print behind Waymo’s
move, too. It mentioned safety drivers
will be present later this year in some
of its autonomous Chrysler Pacifica
minivans, purportedly for the purpose
of generally expanding the driverless
taxi service to meet demand.
Maybe Waymo’s methods are more
measured than those of Mr. Musk. But is
there not similar potential — and perhaps
intent — for fooling the public about
what self-driving truly means?
