Driverless Cars good or bad? Google Cofounder Sergey Brin envisions a time when no one will buy cars anymore because of public driverless cars. He believes it would change the world we are living due to less fuel use, not spending money on automobiles, and more flexibility than buses. We have often seen such a thing on tv or movies but will it ever play a big role in our generation of time.

The idea of even testing a driverless car started in the 1950's by General Motors. GM started with a car that had a "Smart Road" designed for it, the road had electrical cable giving radio signals to the car leading it too its destination. The smart roads was a great idea but it was just too expensive for all roads to get upgraded. The smart roads wasn't in the budget so the cars had to get smarter? Google's first modified smart car was a Prius with many sensors but the biggest sensor of all was on the roof of the LIDAR it used lasar beams to give the car a 3D model of its surroundings.

The smart car has its goods and bads to it, one bad is that cars will never truely be driverless because in case of an emergency the driver must take over. What will happen if a driverless car causes an accident or injury? Who will take the blame, the owner or the manufacturer of the vehicle? That's a huge WHAT IF . The cars still don't know how to drive thru or around acidents or construction zones. My position on driverless cars would have to be NO until we have laws for the driverless cars such as who to blame or if no one is paying attention while the car drives. Engineers must take their time on these smart cars so they are reliable, safe, and Intelligent enough to drive through obstacles on the road. What I'm trying to say is that perfection takes time and the engineers are rushing the cars right now, so companys will make money. We are not ready for Smart Cars.
