January Newsletter - Driverless Cars

For the past hundred years, innovation within the automotive sector has brought major technological advances, leading to safer, cleaner, and more affordable vehicles. But, for the most part, since Henry Ford introduced the moving assembly line, the changes have been incremental, evolutionary. Now, in the early decades of the 21st century, the industry appears to be on the cusp of revolutionary change—with potential to dramatically reshape not just the competitive landscape but also the way we interact with vehicles and, indeed, the future design of our roads and cities. The revolution, when it comes, will be engendered by the arrival of autonomous or “Driverless” vehicles.

Driverless Cars is Vega’s topic of the month. Read an executive summary of our monthly technical review at page 3. The full article is published at our Blog.
Vega newsletter is published monthly by Vega BI, and distributed to our partners to facilitate pursuit of a common interest in top-notch technologies.

Driverless Cars or Autonomous Vehicles

A driverless car is an automobile that has an autopilot system allowing it to safely move from one place to another without help from a human driver. Ideally, the only role of a human in such a vehicle would be indicating the destination.
The implementation of driverless cars could theoretically lead to many improvements in transportation, including:
ï  Reduction in car accidents, autonomous system's increased reliability and faster reaction time
ï  More efficient transportation, Increased roadway capacity , Higher speed limit
ï  increase in road capacity
ï  Relief of vehicle occupants from driving and navigation chores, Removal of constraints on occupants' under age, over age, unlicensed, blind, distracted, intoxicated, or otherwise impaired.
ï  Alleviation of parking scarcity, Reduction of space required for vehicle parking
ï  No need for traffic police and road signage
ï  Greatly reduced mobility costs through car sharing
ï  Simplify introduction of alternative fuels

There are, however, many obstacles to successfully implementing the driverless car as a common and effective method of transportation. This is especially true in situations in which a driverless car would need to safely navigate alongside normal cars directed by human drivers.
In spite of the various benefits to increased vehicle automation, some foreseeable challenges persist:
ï  Liability for damage
ï  Resistance by individuals to forfeit control of their cars, Drivers being inexperienced if situations arose requiring manual driving
ï  Software reliability, A car's computer could potentially be compromised
ï  Implementation of legal framework and establishment of government regulations for self-driving cars
ï  Loss of driving-related jobs
ï  Autonomous cars may require very high-quality specialized maps to operate properly

To be useful, a driverless car must be able to navigate to a given destination based on passenger-provided instructions, avoid environmental obstacles, and safely avoid other vehicles. Some proposed methods for meeting these goals involve developing entirely new transportation infrastructures or substantially altering the existing infrastructures to accommodate driverless vehicles.
One example involves developing a monorail system to which private vehicles can "dock". Upon connection, the monorail would guide the private vehicles to their destinations.
This type of system would simplify navigation and collision avoidance but would require large-scale changes to the existing transportation infrastructures.
Other ideas for the development of a driverless car only involve the development of a new type of car and do not require any infrastructure changes. Such vehicles would operate like traditional human-directed vehicles and would not require more than minor infrastructure changes. For this type of driverless car to work, it would need to have access to some form of guidance system that would direct it to its destination. It would also need a short-range guidance system that would allow it to safely navigate through traffic without endangering its passengers or other drivers on the road.
There are many potential advantages to using a driverless car instead of a traditional human-controlled vehicle. A driverless car would not be subject to human error, one of the most common causes of car accidents. There would be little need for driver's licenses, highway patrols, extensive traffic laws, and even stop signs or street lights. Such vehicles would not be affected by jerky or erratic human drivers and would, therefore, be able to drive very close together. This could lead to a situation in which high road density would not have a detrimental effect on speed, so many cars could travel close together while maintaining a high average speed.

Conclusion
Autonomous cars will greatly impact on our lives. They will make driving safer, more convenient, less energy-intensive and cheaper. They will greatly reduce our CO2 footprint, enhance our freedom and reduce the risk of dying in a traffic accident. They will force us to confront philosophical issues about us and the machines we have created and they will change patterns of work, life and economic organization. Although the benefits are obvious, the current legal framework is still hindering the further evolution of this technology and may thus be responsible for hundreds of thousands of deaths per year which would have been prevented if autonomous cars had reached maturity earlier.
It is time to seriously consider this technology and to put it into service to the benefit of our societies.
