Smart cars, Intelligent highways

Nowadays scientifics create a lot of intelligent things to make our lives better and easier, and also to protect the enviroment. One example or things that make our lives easier are smart phones, some years ago you needed a camara to take pictures, a computer to navegate on the internet and a telephone to make calls, but now you can do all these things just using a smart phone. The same happens with smart huses which you can turn on or off the airconditioner or the lights, lock and unlock doors and windows using acontrol or your voice.

There are also smart things that protect the enviroment like electric cars which -of course- use electricity instead of fuel in order to reduce pollution.
