Remember those 1980s cars that used to tell you "Your door is ajar"?Even aside from sounding like someone who only knows the punchline but not the setup of an old joke ("When is a door not a door?") those voices annoyed almost everyone. Which is why, for many years, most cars didn't talk.But increasingly, they're talking now. And we're talking more to them. There are voice-activated music systems, hands-free telephones, and even GPS navigation systems you can ask questions. As computers take over more and more systems in cars, they're going to need to communicate even more information...and humans' preferred method of communication is talking.That's where communication and sociology researcher Clifford Nass of ...

This evening in the car my six-year-old daughter, Alice, commented out of the blue that she wished our car could drive itself.“I’d like that, too,” I said, and explained that scientists were, in fact, working on cars that could do exactly that, thinking of the Grand Challenges for driverless cars held by the Defense Advanced Research Projects Agency over the past few years.“You should get one,” she said. I explained I couldn’t buy one yet, but maybe she could when she’s grown up.“That would be cool,” she said.Then I got home, started looking for a topic for this week’s science column, and the first item that popped up was
John Tierney’s ...

Get my column as a podcast.***Going on a long car trip this summer? Planning to make good time? Going to drive all night, maybe?Well, don’t.Statistics are somewhat unreliable, because there’s no good way to test for it, but it’s estimated that about 16 percent of all vehicle accidents are caused by driver fatigue. That’s 35,000 accidents a year in Canada.Back in 2000, Alistair MacLean, head of the psychology department at Queen’s University, published a study that found that sleep-deprived drivers were just as impaired as drunk drivers.MacLean studied the driving performance of men and women with good sleep habits. He asked them ...

...how about a car that
runs on compressed air?Most importantly, it is incredibly cost-efficient to run – according to the designers, it costs less than one Euro per 100Km (about a tenth that of a petrol car). Its mileage is about double that of the most advanced electric car (200 to 300 km or 10 hours of driving), a factor which makes a perfect choice in cities where the 80% of motorists drive at less than 60Km. The car has a top speed of 68 mph. Refilling the car will, once the market develops, take place at adapted petrol stations to administer compressed air. In two or three minutes, and at a cost of approximately ...

Remember the
X-Prize, the $10 million (U.S.) reward offered to any team that could create a privately funded-and-built spacecraft capable of lifting three humans to a sub-orbital altitude of 100 kilometres on two consecutive flights within two weeks?
Of course you do. One of the 23 competing teams, the daVinci Project, was supposedly poised to turn Kindersley into a spaceport...but alas, SpaceShipOne, designed and built by legendary aircraft designer Burt Rutan’s Scaled Composites, Inc., got there first, and took home the cash.
But the competition was so successful it sparked a whole new interest in prizes for various technological advancements...or, maybe, revived an old interest.
The X-Prize drew its inspiration from the hundreds of aviation prizes offered between 1905 and 1935, including ...

With summer officially here and school officially out, the roads will soon be full of people driving to and from the beach, the cottage and/or grandma’s house. Just in time, new research has appeared that sheds new light on how drivers can best keep their minds--and, as a result, their cars--on the road.
First, some figures. A National Highway Traffic Safety Administration survey in the U.S. last year found that the majority of drivers engage in at least two of 12 distracting behaviors on some driving trips: 81 percent reporting talking to other passengers and 66 percent reporting changing radio stations or looking for CDs or tapes.
Nearly half reported eating or drinking while driving, while ...

We bought a new car a little over a year ago, and while choosing what make of car to purchase naturally took weeks of research and consideration, it took us almost as long again just to decide on what colour of car we wanted. (We settled on "platinum green.")
Painting an automobile involves many coats of paint, starting with an initial "electrocoat" designed to bond well to bare metal; that's followed by a primer, which provides a smooth base for subsequent coast, a colour coat, which may also provide special effects such as a metallic sheen, and a clear coat that keeps everything shiny.
All of these layers currently involve solvents--very high levels of solvents, in fact; in standard base ...

Will we be driving gasoline-powered cars 10 or 20 years from now?
Judging by the 2001 Michelin Challenge Bibendum, some of us will, but many won't.
The Challenge Bibendum (Bibendum is the real name of the made-of-tires Michelin Man) offers manufacturers an opportunity to demonstrate alternative-fuel vehicles in real-world conditions.
This year's challenge drew 27 production cars and 18 prototype cars. It included a critique of the vehicles' design at the Automobile Club of Southern California, a performance test at the California Speedway in Fortuna, and a 430-kilometre drive to Las Vegas.
Several different power sources were used. Six cars in the competition didn't use an alternative fuel at all--they used gasoline. Technological improvements ...

Right now, on a dry lake bed in Black Rock, Nevada, two teams are locked in a fierce competition. Using exotic, jet-propelled vehicles, they're striving to break the sound barrier--on land. In the process, they're pushing technology to its limits.
What makes the competition even more interesting is the contrast between the two teams. On the one side is the Thrust SSC (SSC stands for SuperSonic Car), whose design was carefully modelled using computers and wind tunnels before it was ever built. On the other side is the Spirit of America, whose genesis was a little more, well, informal. "Yeah, we modeled the car," says crew chief Dezso Molnar. "We modeled it for about 42 seconds on ...
