These cars have a good effect as well as a bad. The smarter cars focus on keeping the drivers, passengers, and pedestrians safe. You may be asking yourself, "is it really a safer option?" Yes it is. These cars require little to no human control, They have all kinds of sensors, and are well tested before sold.

These cars requiring little human control is a good thing. All the human has to do is watch the road. Most accidents are caused because someone brakes to fast or speeds and hits another car. With the smart cars the human won't be in control of any of that. The car will drive 25 mph avoiding speeding tickets and accidents. The driver will be prepared to take over any time the car does not succeed.

It cant get safer than senors. These cars have a video camera mounted near the review mirror, four automotive radar senors, a gps reciever, and an inertial motion sensor; It can sense every human motion. The senors make sure the driver keeps both hands on the wheel. The seat will vibrate if the car is in danger of backing into an object. The car can steer, accelerate, and brake themselves. They are still improving sensors to make driving safer and leading to cars that can handle more and more driving tasks on their own.

The cars are not just thrown in stores to be sold, they are well tested. In some states you are not even aloud to test them. They will not release any cars without making sure your safty isn't at stake. They are working on liability laws in case of an accident. If someone happens to get hurt because of technology fail, it will be covered.

These cars are very safe. There really isn't any way to get into an accident because of all the senors. You also dont have to worry about getting a speeding ticket. If anything serious was about to happen the car will alert the driver to take over. These cars require little to no human control, they have all kinds of sensors, and are well tested before sold. What could be safer than that?
