It is believed that vehicles such as cars, buses and trucks will run without drivers in the future, c. Consequently, all people will bacome passengers.

While some people are concerned about somevarious problems such as safety, I, however, I think that the benefits of driverless cars would outweigh the drawbacks.

The repetition of "some" sounds a bit clunky, so another word such as "various" fits better :)

There are two main reasons why people are worried about vehicles running without rdrivers.

Firstly, they are worried about the safety of being a passanger in a driverless vehhicles, because there; they do not believe in the driverless technology because they think human drivers would be more experienced than AI.

For example, there is a requirement in driving experience in many taxi industryies.

Secondly, people, especially the drivers, would be afraid to be makde redundant by the development of driverless cars, which means that they would have to find another job or learn a new skill.

"Driverless" is not a noun by itself; you have to say "driverless cars" or "driverless transport :)

However, I believe that people would profit more from vehicles without drivers than thatose with a driver.

As "vehicles" is plural, the plural form of "that" must also be used.

On one handFirstly, becoming a passager can make people feel more relaxed, because driving requires plenty of focussed attention which would easily make poeple feel tiredtires people.

Your original sentence was good, this just flows better. Also I've made a note about "on the one hand" and "on the other hand" below :)

As a result, it can help reduingce accidents caused by fatigued drivers.

On the other handAdditionally, it would be more convenient for thossome people, particularly children and the oelderly, to travel.

"On the one hand" and "on the other hand" are used if you are looking at two sides of an argument. For example "On the one hand, driverless cars are convenient. On the other hand, they may be dangerous and lead to accidents."

You are supporting only one idea, so "Firstly" and "additionally" work better. :)

Also, "elderly" is more polite than "the old".

For instance, there are a lot of mothers in China go twho get their licence in case their children get ill.

In conclusion, it is predicted that there will be no drivers in the future because all the vehicles wouldill be driverless.

Though some people are worried about it, I think the advantages would outwigh the disadvantages.
