Q: Google Maps 
  
 The German automaker Audi has taken its piloted-driving concept car on its first long-distance test drive. The Audi A7 drove from California's Silicon Valley to Las Vegas, a distance of about 550 miles (900 kilometers). 
  
 The car arrived in Las Vegas on Monday night, just in time for the International CES 2015, one of the world's biggest events for electronics and technology. 
  
 The autopilot system allows the car to change lanes and speed ahead of other vehicles but works only up to a speed of 70 mph (110 km/h). 
  
 To navigate, the car used in the test, called "Jack," uses a combination of radar sensors in different positions of the car, two laser scanners, a 3D camera in the front of the vehicle, and four more cameras on the side. 
  
 A team of journalists and car experts were invited to take part in the test, with each journalist traveling about 100 miles (180 km) while sitting in the driver's seat. A professional test driver sat in the passenger seat for added safety, as required by California state law.

 During a ride in Audi's self-driving car along a freeway in Las Vegas at last year's CES, the system failed and the driver had to take over. After a year of development, Audi must feel it solved all the glitches, as it sends an A7 fitted with its self-driving gear on a two-day, 550-mile road trip from the San Francisco Bay Area to Las Vegas, and the 2015 International CES. 
  
 Audi calls its self-driving technology "Piloted Driving," and it has been showing significant advancement with the technology year after year. Now Audi notes that the sensors in the research car, nicknamed Jack, are "production-ready." 
  
 This A7 comes with Audi's standard long-range forward radar, currently used for adaptive cruise control, but also features two rear-facing and two side-facing radar sensors. A laser scanner, or LIDAR, behind the grille serves as a redundant sensor to help the radar with solid-object detection. A 3D camera also looks forward, while four smaller cameras monitor the front and rear views from the corners of the car. 
  
 The information from all these sensors and the car's GPS location get processed by an onboard computer, which can control braking, acceleration and steering. 
  
 Audi notes that the system will work from 0 to 70 mph, but when the car approaches an urban area it will alert the driver to take over manual control. If the driver does not take over within a set amount of time, the car will turn on its flashers and pull over onto the shoulder. While under way on the highway, the A7 can initiate its own lane changes and passes. 
  
 One challenge for the A7's Piloted Driving road trip will be the condition of lane lines, which the car will monitor to help guide its path. If lane lines disappear due to road construction or weathering, the car will need to rely on its GPS and relative distance from other traffic around. 
  
 The urban environment limitation also suggests that Audi has not refined the system enough for the many obstacles and threats of city driving. However, the system Audi described, if it works as intended, could be a feature available on production cars within a very few years, helping drivers make long freeway trips.

When it was time to exit, I pressed the same two buttons on the steering wheel and took control again. 
  
 "The technology is coming along quickly," said Daniel Lipinski, one of several Audi engineers who developed the automaker's piloted driving technology. "You can see that this is a natural next step to the other driver assistance systems already being developed."

 Audi's system is intuitive, easy to use and in many ways does feel like what we'll expect from the next generation of cruise control. 
  
 20 sensors and cameras built into the A7 concept car let the car measure where other cars and trucks are on the highway, how fast they are travelling and when the Audi should lane change or alert you, as the driver, to take control of the car and resume manual driving. 
  
 "Our goal is to make driving safer," said Lipinski who has logged many of the 50,000 miles Audi has put into developing piloted driving software. "We need to show the technology is safe and is a benefit and show we can be ready under certain situations." 
  
 Audi allowed me and handful of other journalists to test drive the A7 with piloted driving technology only after we were licensed by the state of California for this one-time road trip. 
  
 Ultimately, it will be up to state regulators to determine when a feature like Audi's Piloted Driving technology is ready to be included in the cars and trucks we buy. Before that happens there will be a lot of debate about how much piloted driving on the highway will encourage drivers to pay even less attention when they're behind the wheel. 
  
 But already, industry veterans like John Krafcik, the President of TrueCar, see how systems that offer driver's the next level of cruise control will be in demand. 
  
 "I think car buyers are going to want this type of technology," said Krafcik. "Why not? If it can make driving on the highway safer and pay attention if you're not, a lot of people will find that appealing."

It feels like something out of a sci-fi movie—a luxury car that can drive itself 550 miles, from Silicon Valley to Las Vegas. But this is not a movie: Over two days, an Audi A7 Sportback (nicknamed "Jack") made the trip with little human help, its journey aided by GPS and radar sensors that feed data to an onboard computer. This system ensures the car changes lanes, overtakes vehicles, and accelerates, steers, and brakes safely, CNET explains. The car isn't completely independent, though—the autopilot only works up to 70mph and doesn't function in urban areas, reports Popular Mechanics. When a human needs to take the wheel, the car lets off a warning; if there's no response, it pulls over to the shoulder and comes to a stop with flashers on. Jack's journey was completed last night, according to Business Insider. However, there's bound to be debate about this "Piloted Driving" technology breeding even more inattentive drivers, notes CNBC, and state regulators need to get on board before such cars become mainstream. But industry insiders say the public is ready. "Why not? If it can make driving on the highway safer and pay attention if you're not, a lot of people will find that appealing," one tells CNBC. And that's the point—to "make driving safer," an Audi engineer says. The A7's solo trip is part of the 2015 International Consumer Electronics Show.
