In today's tech-filled world, it's no surprise that the vehicles of today are loaded with technology. But while we are seeing more and more new features, some classic features are going extinct. We have the top five features that are disappearing from cars.

1.  Keys.  Cars with keyless entry and "start" buttons are beginning to dominate the market.

2.  Crank windows.  Unless it's the cheapest one on the lot, pretty much any new car has automatic windows now.

3.  Long antennas.  They've been replaced by shorter, more compact antennas that can also handle GPS and telephone signals.

4.  Manual transmissions.  They'll never go away completely.  But more people are buying automatics because the price difference isn't as big as it used to be.

5.  Emergency brakes.  They're being replaced by an electronic feature called "hill hold," which automatically sets a brake when you're stopped on a hill, then releases it when you touch the gas.
