AUTONOMOUS VEHICLES
• Autonomous vehicles are categorized into six
levels of automation, from 0 to 5, as defined
by the Society of Automotive Engineers (SAE).
These levels describe the extent to which the
vehicle’s computer systems can handle
driving tasks, with Level 0 being no
automation and Level 5 being full automation.
LEVELS OF AUTONOMOUS VEHICLES
Level 0 (No Driving Automation): The driver is in complete
control of the vehicle, with no automated features.
Level 1 (Driver Assistance): The vehicle can provide some
assistance, such as adaptive cruise control or lane-
keeping assistance, but the driver is still responsible for
monitoring the environment and making most driving
decisions.
• Level 2 (Partial Driving Automation): The vehicle can
perform both steering and acceleration/deceleration, but
the driver must remain engaged and ready to take over
control.
Level 3 (Conditional Driving Automation): The vehicle can
handle most driving tasks in certain conditions, but the
driver must be prepared to intervene when prompted by
the system.
Level 4 (High Driving Automation): The vehicle can
handle all driving tasks in specific conditions and
environments without driver intervention.
Level 5 (Full Driving Automation): The vehicle can handle
all driving tasks in all conditions and environments
without any human intervention.
• Currently, most commercially available vehicles with
automated features are at Level 2 or below. Level 3 and
above represent significant advancements in
autonomous driving technology and are still under
AUTONOMOUS VEHICLES
• Self-driving or autonomous cars have been
considered as the future of driving for a long time.
Fully autonomous vehicles operating in mixed
traffic will soon become a reality in the
foreseeable future. According to Statista, in 2019,
there were approximately 31 million cars with at
least some level of automation in operation
worldwide. This number is to surpass 54 million
by 2024 end, with the market size of autonomous
cars exceeding USD 61 bn by 2026.
ALL VEHICLES ARE AUTONOMOUS?
But what makes a vehicle autonomous? Are all
vehicles autonomous to the same degree?
• The Society of Automotive Engineers (SAE), a global
professional association and standards organization,
defines 6 levels of driving automation ranging from
0 (fully manual) to 5 (fully autonomous). These
levels have been adopted by the U.S. Department of
Transportation.

1. Level 0 – No automation – This level describes the standard car which has no
extra technology that will alter the vehicle’s driving behaviour by itself. The
driver therefore must drive the vehicle and monitor any possible warnings or
safety activities, and thus the driver is responsible for braking, steering,
accelerating etc.
• 2. Level 1 – Driver assistance – Level 1 is the most basic form of automation.
The vehicle features a single automated system for driver assistance, such as
steering or accelerating (cruise control). Adaptive cruise control, where the
vehicle can be kept at a safe distance behind the next car, can be qualified as
Level 1 because the human driver monitors the other aspects of driving such
as steering and braking. Level 1 autonomy was first seen in the late 1990s with
Mercedes-Benz. Majority of new cars sold today come with this level of tech.
3. Level 2 – Partial Automation – Level 2 is when two or more aspects of
the driving experience are controlled by technology and is the standard
for a lot of high-end vehicles today. Having multiple automated functions
allows the car to change lanes, adjust speed and park all by itself.
However, the driver must still have their hands on the wheel throughout
any of these processes. Here the automation falls short of self-driving
because a human sits in the driver’s seat and can take control of the car
at any time. Tesla autopilot, Cadillac Super Cruise systems are officially at
Level 2 standard.
• 4. Level 3 – Conditional Automation – At this stage, the technology
makes nearly all the decisions on the road. Technologically, this is a big
jump from level 2 as the vehicle can effectively detect the environment
around them and drive by themselves in certain situations. Level 3
vehicles have “environmental detection” capabilities and can make
informed decisions for themselves, such as accelerating past a slow-
moving vehicle. However, they still require human override. The driver
must remain alert and ready to take control if the system is unable to
5. Level 4 – High Automation – This level of automation does not require
any human interaction in most circumstances. Level 4 vehicles can
intervene if things go wrong or there is a system failure. They will be
limited to certain areas (geofencing) where speed limits are low and the
roads are easy to read. These vehicles lend themselves to ride-sharing
taxi services in city areas. There is continuous testing of these cars being
done and also the current regulations are restrictive, hence these cars are
not being widely used as of now. NAVYA, a French company, is already
building and selling Level 4 shuttles and cabs in the U.S. That run fully on
electric power and can reach a top speed of 55 mph. Alphabet’s Waymo
recently unveiled a Level 4 self-driving taxi service in Arizona, where they
had been testing driverless cars.
• 6. Level 5 – Full Automation – This is the category for fully driverless
cars. No assistance is needed from humans at all and so there is no
need for a steering wheel or pedals. These vehicles, in theory, can
perform anything that a standard driver could do. The intelligence and
sophistication of the computers running these cars will mean that they
