LAS VEGAS -- The future of driving is right around the corner.
Hydrogen- and solar-powered vehicles are on the streets. So are cars that can get you through stop-and-go traffic while you sit back and send texts from behind the wheel. Cars are even using radar, ultrasonic waves and cameras to jump into the passing lane and get around slowpokes.
Sure, all of these technologies are still in the testing phase, but that hasn't stopped car makers and technology companies from showing off a new paradigm of driving at the International CES gadget show this week. It's a world in which you no longer grip the wheel with excitement, but instead relax with a book or movie as your car chauffeurs you to your destination.
Though technological innovation isn't an issue, there are many speed bumps on the road to this envisioned future. Consumers must accept the safety and reliability of such systems, governments must draft and pass legislation and the insurance industry needs to draw up guidelines to answer tricky questions such as who'd be at fault in the event of a crash.
"That's one of the biggest issues for the industry as a whole for autonomous technology," said Glen De Vos, vice president of engineering for Delphi's electronics and safety division. "The legal environment has to keep pace. Today we're at the very beginning."
Regulation is a patchwork across the world and within the U.S. Laws regulating autonomous driving have been passed in the U.S. in Florida, California and Nevada - but not nationwide - making it impractical for automakers to sell these super-high-tech vehicles in America. In Germany, computer-assisted driving is allowed but only up to speeds of 10 kilometers per hour (6.2 miles per hour).
"The only thing that is stopping us is the legal stuff," said Patrick Heinemann, an engineer of advanced driver assistance systems for Audi AG.
At the show, the German luxury car maker demonstrated what it could legally: automated parking in a tight squeeze -both on the street and in a garage. The system used laser vision, ultrasonic sensors and a computer that fits in a corner of the trunk. The driver in the demos gets out of the vehicles and holds down a button on his smartphone while the car does the rest, even executing a 3-point turn to avoid dinging adjacent cars. Releasing the button stops the car, to prevent running over something at the last second.
In testing, Audi cars can stay in lanes and advance automatically in stop-and-go traffic that moves at up to 60 kilometers per hour (37 miles per hour), Heinemann said.
