Smarts cars will be successful to the humanity through years, one reason is its technology that will have these cars. it will be able to do everythingh that you might think.
for example it can change the oil by itself, also these systems beep or warm drivers with a voice signal if the vehicle gets too cklose to an object or another vehicle or if it strays of its line.
I think in that way will have less accident in the world becouse there are many careless drivers that get in involved in accident daily.
