Based on the car's speed and distance, the system will warn you of any danger when changing lanes. Coupled with sensors and the use of radar, cruise control also adjusts the throttle and brakes to keep a safe distance between you and the car in front of you when there are changes in traffic speed. The car will immediately alert you of other cars or objects that are in your blind spot if you are trying to change lanes or to park. Cruise control does more than just give your foot a break from a long drive. Sometimes the airbag does more damage than the crash itself. However, a backup camera system is still not a mandatory feature already built into every vehicle. We all know how dangerous the blind spot can be and there would be far less accidents if everyone could afford this system in his or her car. Similar to this system is a lane departure warning. Occupant-sensitive airbags will deploy with the passenger in mind. A wonderful feature that's been popping up on many luxury cars are blind spot and Smooth Running Safe and Reliable Hospital Elevator collision warnings. However, when backup camera systems were first created, they were only available in more expensive cars. Nowadays, you will be given a ticket if someone in your vehicle isn't wearing a seatbelt. It has been around for quite some time. Once any congestion has cleared up, the car will return to its original speed. It can even determine if you are meandering between lanes, such as when you have fallen asleep at the wheel. A backup camera system is not new technology. Airbags can actually be very damaging to smaller and thinner adults. Finally, there are occupant-sensitive airbags. Now it is much easier and cheaper to create them and they are offered for just about every vehicle. Some can detect if you are falling asleep based on a change in posture and head position. But it always takes awhile before luxury features soon become the norm in every car. There are currently features out right now that are offered to those who can afford it, but I hope some of them become mandatory soon, for our own sake.. It can then slow down the car.When cars were first introduced in the market, seatbelts weren't even mandatory. Not every human is the same size or weight. The system will either flash a light, cause the steering wheel or seat to vibrate, or sound an alarm to warn you.It's hard to believe people didn't worry so much about safety in their cars.
