BUFFALO, NY - New cars these days come furnished with some extremely advanced computers, the new features are supposed to make vehicles safer, easier to use and more enjoyable.

More and more are coming with safety features like blind-spot monitoring. One new innovation is a side-view mirror, a symbol lights up to alert you.

And if you drift out of your lane, some cars caution you with a beep.
Consumer Reports Auto Test Center also tests collision-warning systems. New Chrysler 300's beep if you're about to hit something, so you're sure to brake.

Cars like the Audi A8 actually apply the brakes for you. Consumer Reports says tests have shown that these advanced systems can help you avoid an accident and improve your awareness, but they're just no substitute for being alert when you drive.

Some Fords have another new safety feature - inflatable rear seat belts. Ford says these mini air bags built into the seat belts reduce neck and chest injuries.

The new Nissan Altima has a handy feature to help when inflating your tires. When you've got it right, the horn toots.

Properly inflated tires are really important too. They improve fuel economy, they help handling, and they help your tires last longer.

Not all new features are safety related. Like a built-in vacuum coming in the 2014 Honda Odyssey minivan. How about a foot-operated trunk or tailgate release? If your hands are full, just swipe your foot under the sensor - a convenient option being offered on some Fords and BMWs.

Mercedes-Benz is even offering a warning system that's designed to detect if you're in danger of falling asleep behind the wheel. Consumer Reports thinks the concept has potential, but the system hasn't worked all that well in the four models it's tested so far.
