4. Do you think driverless cars will be the cars of the future? Why or why not?

Yes, I believe driverless cars will likely be the cars of the future.
No longer just appearing in blockbuster movies or in the imagination, driverless car technology is gradually becoming a reality in a number of countries around the world, including Vietnam. The development of autonomous vehicles has made significant progress, and many companies are investing heavily in refining this technology. First,driverless cars promise to increase safety and reduce traffic accidents thanks to the feature of automatically predicting and avoiding unexpected obstacles that the driver cannot react to in just a few seconds. Second,driverless cars will save time and increase productivity when traveling on the road, leaving the driver free to use the remaining time to do other things or relax. Finally,they also have the potential to reduce traffic congestion and improve fuel efficiency, as they can communicate with each other to optimize routes and maintain steady speeds. In addition, driverless cars are designed to optimize acceleration and braking performance to increase fuel efficiency while reducing carbon emissions and limiting environmental pollution.
However, it is still limited and not really complete, Vietnamese law still has no legal regulations or mention of driverless cars. Regardless, the benefits of driverless cars make them likely to become a common means of transportation in the future.
