If you want to confuse a teenager today, really take them out of their element, you could do worse than to plop him or her in a 1970 Chevelle or a vintage Lincoln Town Car.
Looking around at the ashtrays, crank windows and manual locks, sitting in what could have been their grandfather's car, they might as well be in another world.
Car design changes quickly, and features that were once standard in just about every car on the road have mostly gone the way of the dinosaur.
Who knows what the future and further advances in auto technology may bring? Perhaps one day the features you take for granted as standards for today's cars may become just as obsolete as these five rarely seen features …
The move to ashtray-free cars began at Chrysler, whose 1995 Cirrus and Dodge Stratus sedans were the first to be sold without ashtrays as standard equipment.
Today, you're much more likely to find a power outlet for a cell phone or MP3 player where the push-in lighter once was, and ashtrays have mostly been replaced by cup holders and storage compartments.
Not only is it a question of an anti-smoking movement, but also of space. According to the Centers for Disease Control and Prevention, about 19.3 percent of adult Americans smoked in 2010 -- roughly 45.3 million people. According to Apple, more than 300 million people have bought iPods. When you add in other MP3 players, iPhones and various other smartphones, it's clear the smokers are simply outnumbered.
But they aren't totally extinct. For $15 to $100, car buyers can get a smokers group option that includes ashtrays and cigarette lighters. Plus, some luxury automakers such as Rolls Royce still include ashtrays for their humidor-owning customers.
