text: On the other side of the spectrum though, there are many disadvantages to having driverless cars. One being, the cars will be very expensive, they have so much new technology that goes into them and so many safety features. The price will set many back from trying to buy one and what would be the use if only the people who did not need them, had them? Next, many mechanics will have to learn a brand new method of fixing driverless cars, more so all the types of sensors and trackers. The learning process can take many months to someone who needs it fixed right now and will set many other from trying to be a mechanic.
