text: Some people daydream when they are driving and forget they are on the road driving and may get into an accident. Or teens like to text and drive (even though it is against the law to do that) the smart cars will help when a collision may happen. The General Motors company have a vibrating seat that alerts people when something is happening that they should watch out for. So whenever you are in a daze and you are coming close to hitting a tree the seat will vibrate hard enough for the driver to realize what they are doing. Even though the driverless car may need help sometimes trying to get through traffic jams and it would need your assitance, but the car is still worth getting considering that it can drive by itself 90% of the time.
