Self-Driving Cars: The Future
In 2019 4,400,000 people were involved in car accidents that were serious
enough to require medical attention within the United States (about 1.34% of
Americans). 38,800 of these injuries resulted in death (National Safety Council). A large
majority of these cases are caused by distracted driving, over ¼ of these incidents
alone are caused by texting and driving. Over the years, many alternatives have been
mentioned, one of which being self-driving cars. Self-driving cars take away the aspect
of distracted driving, making your level of sobriety, awareness, and fatigue, all negligent
factors. Eating a sandwich in your car will no longer put you at risk of being involved in
an accident. Self-driving cars have the opportunity to save thousands of lives every year
and should be more accepted in society as a real solution.
To begin with, self-driving cars have three primary types of sensors, camera,
radar, and LiDAR. Camera sensors detect RGB information (colors) in the surroundings
(Badue). However, these sensors can be blinded by sunlight and cannot detect contrast
and depth. Radar sensors can detect range information, and unlike camera sensors,
radar can detect in harsh and extreme weather conditions. LiDAR sensors are the most
accurate of the three, being able to detect depth to a precise distance. The only
downside is they do not work as well as radar sensors in bad weather conditions. In an
article about public ethics and health of autonomous (self-driving) cars, Jane Fleetwood,
Ph.D., discusses the application of these sensors, “Autonomous vehicles constantly
obtain information from their environment, using a variety of sophisticated cameras and
sensors that rely on ultrasound, radar, and laser-based ranging, or “lidar.” A variety of
advanced technologies enable autonomous vehicles to correct for human mistakes and
“learn” from the “experience” of other autonomous vehicles. Because all store sensor
data, engineers are able to reconstruct events of a crash and examine what the vehicle
sensed through its multiple inputs and analyze the logic it used to determine its course.”
Using all three of these sensors, self-driving cars are able to work precisely and
accurately in all weather conditions, better than humans can. Also, through vigorous
testing, they have been refined to make tough decisions in dangerous situations.
Furthermore, as briefly being alluded to in the previous paragraph, self-driving
cars go through tremendous amounts of testing. With only four main factories known as
“Gigafactories,” Tesla has a total of 48,016 employees as of December 2019. The
number of hours that go into engineering, testing, and manufacturing these vehicles is
remarkable. About 2 hours outside of Fairbanks, Alaska in the town of Delta Junction is
Tesla’s Winter Testing Facility. With an average high temperature of below 0 degrees
Fahrenheit in winter months and having year-round ice and snow, Tesla scientists and
engineers test their electric cars and their self-driving capabilities at this facility. Tesla is
an electric car company founded in Palo Alto, California by its CEO Elon Musk. They
are currently the front runner in the self-driving car industry. A reporter, Tim Stevens,
was invited to this facility to check it out and said “The best place to test this was on the
massive snowfield, just off the back straight of the oval. That means you can easily
drive into snow at triple-digit speeds if you're feeling randy. With a laptop and a few
clicks, one of Tesla's engineers shut off all the car's stability systems and invited me to
do an emergency lane change at 65 mph, the sort of thing you may have to do in Alaska
when encountering a wayward moose who's on the hunt for some trimmed greens.”
Stevens talks about the sheer conditions these cars are tested in and the remarkable
decisions they can make in extreme circumstances. This is just one example of the
amount of testing that goes into perfecting these cars.
On the contrary, one counterargument to this hypothetical utopia of self-driving
cars is that self-driving cars cannot make decisions as well as humans. One metaphor
for this idea is the trolley problem, which goes as follows. A train is on a track with five
people on it, and the only way to save the 5 people is to pull a switch to put the train
onto a path with only one person. Do you pull the switch or not? This is the trolley
problem (Nyholm). This idea can be applied to a self-driving car. How do you program
Artificial Intelligence to make a decision like this?
While at first, this seems like an unsurpassable dilemma. However, finding a
solution to this problem is extremely realistic. Scenarios that are as black and white as
the trolley problem do not occur with self-driving cars. No human or Artificial Intelligence
can accurately predict the outcome of deciding on a dangerous scenario. However,
Artificial Intelligence can use data it has stored from extensive testing and can perform
thousands of calculations in a split-second to quickly calculate the safest scenario. This
would be far safer than any decision a human could make under pressure. In an article
about applying the trolley theory to self-driving cars, Sven Nyholm said, “This does not
carry over to the case of self-driving cars. Rather, the decision-making about self-driving
cars is more realistically represented as being made by multiple stakeholders – for
example, ordinary citizens, lawyers, ethicists, engineers, risk-assessment experts,
car-manufacturers, etc. These stakeholders need to negotiate a mutually agreed-upon
solution. And the agreed-upon solution needs to be reached in light of various different
interests and values that the different stakeholders want to bring to bear on the
decision.” Agreeing on a solution to this issue is extremely achievable. This is a very
small dilemma to overcome for being a technological development that has so many
benefits.
Lastly, self-driving cars have the potential to save thousands of lives a year.
“Autonomous vehicles, which could reduce traffic fatalities by up to 90% by eliminating
accidents caused by human error—estimated to be 94% of fatalities—could save more
than 29 000 lives per year in the United States alone. Around the world, autonomous
cars could save 10 million lives per decade, creating one of the most important public
health advances of the 21st century” (Fleetwood). This data shows the urgency of
implementing self-driving cars into our everyday lives. If 90% of accidents can be
eliminated, there needs to be an urgent push for implementing these vehicles into our
society.
Clearly, self-driving cars need to be more accepted by society. Self-driving cars
sadly have a false stigma of being unsafe, inaccurate, and unpredictable. The truth is,
self-driving cars and their technologies have been tested to such an extent that they are
safer in every way than human driving is. Hopefully, in the future, self-driving cars will
be a staple in society, and the accident rate and fatality rate will drastically decrease.
