Welcome to brain Stuff from How Stuff Works, Hey, brain Stuff,
Lauren Vogel bomb here. Imagine a future in which you
climb into the back of your self driving autonomous vehicle
and instructed to take you on a late night fast
food run. Imagine also that you're particularly famished that night.
Would you be able to tell the computer to exceed
(00:22):
the posted speed limit and get you to your chicken
nuggets a little more quickly? Or will the system remind
you in a polite but firm, synthesized voice that you
have can. That's a hard question to answer, since level
five autonomous vehicles, the hypothetical ones equipped to be able
to drive in any sort of environment with no human intervention,
are still somewhere away off in the future. But it
(00:43):
seems likely that when robotic cars hit the market, they'll
be designed to stick to speed limits, except perhaps when
safety requires speeding up. A few years back, when experimental
autonomous vehicles first began appearing on American roads, Reuters reported
that Google's self driving cars actually were design end to
go up to ten miles or sixteen kilometers faster than
the speed limit when traffic conditions made it necessary. The
(01:06):
problem wasn't that the robots got unpatient, but rather that
human drivers routinely exceed posted speed limits and tend to
go as fast as they think they can get away
with without getting a ticket. Researchers worried that with all
those humans out there careening around as fast as possible,
it might be dangerous for robots to plod along at
the legal limit or lower, but so far there aren't
(01:26):
any signs that autonomous cars are prone to speeding. In California,
the only state that keeps track of accidents involving autonomous vehicles,
there have been nearly fifty mishaps reported since, and many
of them it was a human driven vehicle that rear
ended an autonomous one, often when the robot cautiously slowed
tield to another car or a pedestrian. In other instances,
(01:47):
human drivers got frustrated with slow poke autonomous vehicles and
clipped them as they tried to pass. According to report
on Speed limits by the National Conference of State Legislatures,
government traffic planners envision a few sure in which autonomous
vehicles will most likely be programmed to not exceed the
posted speed limit in an area. Moreover, they're hoping that
(02:07):
regimentation will make the road safer because it will reduce
the danger that develops when the roads are filled with
vehicles traveling at varying rates of speed. On the downside,
the author's note, a proliferation of law abiding robots will
mean a reduction in the revenue that state and local
governments have been getting from ticketing speeders. But if we
ever get to the point where we have enough self
driving cars on the road that we could have robot
(02:29):
only highway routes, networked vehicles might be able to travel
safely at higher speeds than human drivers, and University of
Illinois researchers say that because autonomous vehicles are designed to
adjust to and accommodate human drivers maneuvers, even a small
proportion of robots driving out a highway as few as
five percent of total cars could eliminate the stop and
go waves that lead to congestion. Today's episode is written
(02:56):
by Patrick J. Keiger and produced by Tristan McNeil. For

The Burden
The Burden is a documentary series that takes listeners into the hidden places where justice is done (and undone). It dives deep into the lives of heroes and villains. And it focuses a spotlight on those who triumph even when the odds are against them. Season 5 - The Burden: Death & Deceit in Alliance On April Fools Day 1999, 26-year-old Yvonne Layne was found murdered in her Alliance, Ohio home. David Thorne, her ex-boyfriend and father of one of her children, was instantly a suspect. Another young man admitted to the murder, and David breathed a sigh of relief, until the confessed murderer fingered David; “He paid me to do it.” David was sentenced to life without parole. Two decades later, Pulitzer winner and podcast host, Maggie Freleng (Bone Valley Season 3: Graves County, Wrongful Conviction, Suave) launched a “live” investigation into David's conviction alongside Jason Baldwin (himself wrongfully convicted as a member of the West Memphis Three). Maggie had come to believe that the entire investigation of David was botched by the tiny local police department, or worse, covered up the real killer. Was Maggie correct? Was David’s claim of innocence credible? In Death and Deceit in Alliance, Maggie recounts the case that launched her career, and ultimately, “broke” her.” The results will shock the listener and reduce Maggie to tears and self-doubt. This is not your typical wrongful conviction story. In fact, it turns the genre on its head. It asks the question: What if our champions are foolish? Season 4 - The Burden: Get the Money and Run “Trying to murder my father, this was the thing that put me on the path.” That’s Joe Loya and that path was bank robbery. Bank, bank, bank, bank, bank. In season 4 of The Burden: Get the Money and Run, we hear from Joe who was once the most prolific bank robber in Southern California, and beyond. He used disguises, body doubles, proxies. He leaped over counters, grabbed the money and ran. Even as the FBI was closing in. It was a showdown between a daring bank robber, and a patient FBI agent. Joe was no ordinary bank robber. He was bright, articulate, charismatic, and driven by a dark rage that he summoned up at will. In seven episodes, Joe tells all: the what, the how… and the why. Including why he tried to murder his father. Season 3 - The Burden: Avenger Miriam Lewin is one of Argentina’s leading journalists today. At 19 years old, she was kidnapped off the streets of Buenos Aires for her political activism and thrown into a concentration camp. Thousands of her fellow inmates were executed, tossed alive from a cargo plane into the ocean. Miriam, along with a handful of others, will survive the camp. Then as a journalist, she will wage a decades long campaign to bring her tormentors to justice. Avenger is about one woman’s triumphant battle against unbelievable odds to survive torture, claim justice for the crimes done against her and others like her, and change the future of her country. Season 2 - The Burden: Empire on Blood Empire on Blood is set in the Bronx, NY, in the early 90s, when two young drug dealers ruled an intersection known as “The Corner on Blood.” The boss, Calvin Buari, lived large. He and a protege swore they would build an empire on blood. Then the relationship frayed and the protege accused Calvin of a double homicide which he claimed he didn’t do. But did he? Award-winning journalist Steve Fishman spent seven years to answer that question. This is the story of one man’s last chance to overturn his life sentence. He may prevail, but someone’s gotta pay. The Burden: Empire on Blood is the director’s cut of the true crime classic which reached #1 on the charts when it was first released half a dozen years ago. Season 1 - The Burden In the 1990s, Detective Louis N. Scarcella was legendary. In a city overrun by violent crime, he cracked the toughest cases and put away the worst criminals. “The Hulk” was his nickname. Then the story changed. Scarcella ran into a group of convicted murderers who all say they are innocent. They turned themselves into jailhouse-lawyers and in prison founded a lway firm. When they realized Scarcella helped put many of them away, they set their sights on taking him down. And with the help of a NY Times reporter they have a chance. For years, Scarcella insisted he did nothing wrong. But that’s all he’d say. Until we tracked Scarcella to a sauna in a Russian bathhouse, where he started to talk..and talk and talk. “The guilty have gone free,” he whispered. And then agreed to take us into the belly of the beast. Welcome to The Burden.
