COMMENT 7:ELECTRIC CARS

 Technology advances more and more.Cars ares a good invention,        designed to drive on its own  It is a very useful and comfortable invention.

A driverless car is a vehicle that has a self-driving system to move safely from one place to another without the help of a human driver. All the human has to do is indicate the destination.
The autonomous car is designed to be driven alone, without a driver. This means that    passengers don't have to pay attention to the road  , that they can relax during the journey and spend that time doing other things.
This type of transport has been developing in recent years, there are cars that already park only in difficult places.

This has its advantages and disadvantages like all the advantages of a car without a driver are: these cars will not be threatening.
There will be fewer traffic problems and fewer accidents.
And the downsides: they are very expensive and very few people will buy them.
The work of taxi drivers, delivery men, truck drivers ... the jobs of these workers will disappear

In my opinion, this type of car is a good idea to avoid accidents, but first you should test them if they are 100% safe and see that the system works well and once they are safe on the road and finally prepare them for sale.
