Autonomous Car: Miraculously Self Driving!
                     Autonomous Car: 
Miraculously Self Driving!
Autonomous Car
• A self-driving car (sometimes called an 
autonomous car or driverless car) is a vehicle 
that uses a combination of sensors, cameras, 
radar and artificial intelligence (AI) to travel 
between destinations without a human operator.

Navigate without human intervention
• To qualify as fully autonomous, a vehicle must be 
able to navigate without human intervention to a 
predetermined destination over roads that have 
not been adapted for its use.

Companies Developing Autonomous Car
• Companies developing, testing autonomous cars 
include Audi, BMW, Ford, Google, General 
Motors, Tesla, Volkswagen and Volvo. 
• Google's test involved a fleet of self-driving cars 
including Toyota Prii and an Audi TT navigating 
over 140,000 miles of California streets and 
highways.

How Autonomous Cars Work?
• AI technologies power self-driving car systems. 
Developers of self-driving cars use vast amounts 
of data from image recognition systems, along 
with machine learning and neural networks, to 
build systems that can drive autonomously.

Neural Networks
• The neural networks identify patterns in the data, 
which is fed to the machine learning algorithms. 
• That data includes images from cameras on self-
driving cars from which the neural network 
learns to identify.

 Self-driving features
• Hands-free steering centers the car without the 
driver's hands on the wheel. 
• Adaptive cruise control (ACC) down to a stop 
automatically maintains a selectable distance 
between the driver's car and the car in front.
• Lane-centering steering intervenes when the 
driver crosses lane markings.

Levels of autonomy in self-driving cars
• Level 1: An advanced driver assistance system (ADAS) 
aid the human driver with steering, braking or 
accelerating, though not simultaneously
• Level 2: An ADAS that can steer and either brake or 
accelerate simultaneously while the driver remains fully 
aware behind.
• Level 3: It can perform all driving tasks under certain 
circumstances, such as parking the car. 
• Level 4: An ADS can perform all driving tasks and 
monitor the driving environment in certain 
circumstances. 
• Level 5: The vehicle's ADS acts as a virtual chauffeur 
and does all the driving in all circumstances.

Pros of self-driving cars
• The top benefit touted by autonomous vehicle 
proponents is safety. 
• A U.S. Department of Transportation (DOT) and 
NHTSA statistical projection of traffic fatalities for 
2017 estimated that 37,150 people died in motor 
vehicle traffic accidents that year.

Cons of self-driving cars
• Riding in a vehicle without a driver behind the 
steering wheel may be unnerving at least at first. 
• But as self-driving capabilities become 
commonplace, human drivers may become 
overly reliant on the autopilot technology.

Self-driving car safety and challenges
• Autonomous cars must learn to identify countless 
objects in the vehicle's path, from branches and 
litter to animals and people. 
• Other challenges on the road are tunnels that 
interfere with the Global Positioning System 
(GPS), construction projects that cause lane 
changes or complex decisions.
