What will happen in the future? Driver, is it valid in 2022?
Self-driving car prototype has no steering wheel, brake or accelerator pedals. So how safe is it, and what is it like on the road? The future trend of car/lorry is driverless is unveiled a brand new self-driving car prototype on Tuesday; the first company to build a car with no a steering wheel, accelerator or brake pedal.
Self-driving car prototype has no steering wheel, brake or accelerator pedals. So how safe is it, and what is it like on the road? The future trend of car/lorry is driverless is unveiled a brand new self-driving car prototype on Tuesday; the first company to build a car with no a steering wheel, accelerator or brake pedal.
The car's arrival marks the next stage in
self-driving car project, which was born from the Darpa Grand Challenges for
robotic vehicles in the early 2000s. Kick started its own self-driving car
project in 2008, and it has been rumbling on ever since, first with modified
Toyota Prius and then with customized Lexus SUVs, which took the car’s existing
sensors, such as the cruise-control cameras, and added a spinning laser scanner
on the top.

It is the first truly driverless electric car
prototype built to test the next stage of its five-year-old self-driving car
project. It looks like a cross between a Smart car and a Nissan Micra, with two
seats and room enough for a small amount of luggage.
It is the first real physical incarnation of vision
of what a self-driving car of the near future could be. It operates in and
around California, primarily around the Mountain View area where Google has its
headquarters.
It ferries two people from one place to another without
any user interaction. The car is summoned by a smartphone for pick up at the
user’s location with the destination set. There is no steering wheel or manual
control, simply a start button and a big red emergency stop button. In front of
the passengers there is a small screen showing the weather, the current speed
and a small countdown animation to launch.
Once the journey is done, the small screen displays
a message to remind you to take your personal belongings – reinforcing that
this is not aiming to be a substitute for your personal car at the moment, but
more as a replacement for the taxi without the human driver.

Very few people outside have been allowed to ride in
the new car. Most of the people depicted in promotional videos for the new car
described the experience as “smooth” and “nothing that feels the least bit
threatening”.

Recode were
one of the few independent test riders,
who described the car as having “ample” room despite being small, likely due to
the lack of the normal controls taking up space in the cabin, and "that
this felt a lot like a theme park ride".
Designed the car from scratch, starting with the
sensors and a frame to interconnect them, then adding a cabin that does not
block any of the sensors or create blind spots and eventually the body shell.
The manufacturing of the 100 or so prototype cars will be done by a firm in the
Detroit area, but declined to comment on which.
How does it work? Powered by an electric motor with
around a 100 mile range, the car uses a combination of sensors and software to
locate itself in the real world combined with highly accurate digital maps. A
GPS is used, just like the satellite navigation systems in most cars, to get a
rough location of the car, at which point radar, lasers and cameras take over
to monitor the world around the car, 360-degrees.
The software can recognize objects, people, cars,
road marking, signs and traffic lights, obeying the rules of the road and
allowing for multiple unpredictable hazards, including cyclists. It can even
detect road orks and safely navigate around them.

The new prototype has more sensors fitted to it that
can see further (up to 600 feet in all directions) and in greater detail than
the ones available on the previous repurposed Lexus and Toyota vehicles.
Safety for driverless are the new car is the next
evolution of self-driving car. While the new frame is untested, the company’s
previous versions have clocked up over 700,000 miles of testing on public
roads, mainly around California, including over 1,000 miles of driving in the
most complex situations and cities like San Francisco’s hills and busy streets.
The car itself is limited to 25 mph, which restricts
it to certain roads, but also minimizes the kinetic energy it could carry into
a crash if one should happen. The front of the car is also made to be as kind
to pedestrians as possible with a foam bumper and a flexible windscreen that is
designed to absorb energy from an impact with a person’s body.
Seat belts are also provided – a safety requirement
for vehicles on the road – while the car has redundant systems, a “fault-tolerant
architecture” as calls it, for both steering and braking, should the primary
systems fails; plus that emergency stop button that passengers can hit at any
time.
Self-driving car has also taken the data and behaviors
it learned from its previous vehicles to create a defensive, considerate
driving style that is meant to protect both the passengers and other road
users. For instance, the car will wait a second after the traffic lights turn
green before it moves off, although this could incur the anger of drivers stuck
behind it.
Self-driving car also says that making it drive in a
natural and predictable way has been one of the key goals, so that it behaves
in a familiar way on the road for other drivers.

laser sensor on the roof constantly scans the surroundings.
Now has gone as far as it can with the current
customized vehicles and that a new platform is needed to take the project and
technology to the next step and closer to a product people can actually use.
For instance, the previous generation Lexus vehicle
had blind spots right up against the car where the sensors couldn’t see,
something that needs to be eliminated in any vehicle open to the public.
The cars will first be used to test the software
driving the car and push its capabilities. Says at some point, when it deems
its software safe, it will start putting real people into the cars beyond
Google engineers. It will use the cars in a similar manner to the company’s
Google Glass explorer programme, analyzing how people use them and what works
and what doesn’t.
Designed of the car’s cute looks and friendly “face”
were created intentionally to be “very Googley” according to its designers, to
put both other road users and passengers at ease with the new technology. The
shell is also designed to give the sensors the best view of the surroundings.
The car on the inside, the new car has two
traditional car seats, primarily because in this iteration passengers have to
be strapped in like they would in any other car to meet safety regulations,
which means using standard seat belts. It also provides a more familiar
passenger experience, which at this stage is likely important to aid adoption.
