Autonomous vehicles are slowly becoming a thing of the present rather than just the future. There are several things that must be taken into consideration when it comes to self driving cars. Things like safety, customer base, retail price, and the positive/ negative affects of autonomous vehicles.

First off, How safe do you feel on a rollercoaster or on something that you aren't controlling? You might get that nervous feeling when you first step foot in a self driving car. These vehicles need to be safer than a rubber room, because if not, who's going to step up and take the blame for a gruesome accident? I can forsee lots of drivers blaming/ sueing self driving car compaies for that exact reason. Most of the companies who are developing self driving cars are giving the driver the option to take over when neccessary. They actually reccomend you take over whenever you feel danger on the road. To get these things on the market there are several steps that must be taken, including, driving laws.

In many states, testing of autonomous vehicles is illegal. California, Nevada, Florida, and the District of Columbia have been allowed limited testing on such vehicles. More states will join in once its proved that these cars are reliably safe. They can steer, brake, and accelerate by themselves but are programmed to give control to the driver whenever it is needed. Drivers must be alert at all times in order for these to be successful. People might think this is an easier way of driving, which it is but it doesn't take away the fact that you could still be badly injured or even killed. So alertness is always required.

I think these vehicles could be a hit but several crucial details need to be straightened out before any everyday customer can purchase one. The leading companies on this project are very far away from making autonomous vehicles a hit among mainstream drivers but, I do believe sometime in the future we will have the option to purchase a self driving car.
