Each year, 1.3 million people worldwide die in car accidents. Ninety-four percent of those crashes are due to human error. This is a tragedy that self-driving vehicles can help prevent. That’s because computers can think better and react earlier than people.
As soon as we can show that a self-driving car can drive more safely than a human, we should expect to see many more such vehicles picking up passengers across the country-and eventually around the world.
Self-driving cars will also help speed up the shift towards increased ride sharing and reduced car ownership. Many people already use ride-sharing services instead of owning their own cars. Self-driving vehicles are a great fit for ride sharing because machines have the potential to find the best routes for getting people to their destinations more safely and faster than human drivers.
A future in which more of us use ride sharing as our primary mode of transportation means.we’ll need fewer cars overall, which comes with key benefits, including reduced road congestion and less time wasted in traffic.Fewer cars also means less pollution and fewer parking spaces. That would make room for more parks, bike lanes, and businesses.
Real-world testing is critical to getting this technology ready for nationwide use. That’s why some companies are testing self-driving cars in Pittsburgh, Pennsylvania, and Tempe, Arizona.Both cities have welcomed this technology with open arms.
A better future is within reach. We already have the technology. While it won’t happen overnight, self-driving cars will be an important part of the future of transportation.
