Will there be a time in our lives when cars don't crash? When we can just sit back and relax and our cars will drive themselves. Auto technology experts say "yes". And they say that some of those advances may happen quicker than you might think. They will require the users to input the name of the destination or the complete address of the location that they want to go and the cars' artificial intelligence takes them there automatically without a driver. They will run on solar power in the daytime and ethanol fuel   at night.

What's more, car insurance will become _ because there will be no more automobile accidents after the year 2025. This is because the driverless car will have all safety methods in place by the car's artificial intelligence to prevent automobile accidents. Global positioning systems will become mandatory   in all newly-manufactured cars after 2010, and will be the most important part in the driverless car. What will prevent the driverless car from crashing?
