The correct answer is: b) Testing phase.
Autonomous vehicles (AVs) are still in the testing phase. They are not yet ready for widespread use on public roads. There are a number of challenges that need to be addressed before AVs can be safely and reliably operated on public roads. These challenges include:
- Technology: AV technology is still in its early stages of development. There are a number of technical challenges that need to be addressed, such as how to handle unexpected situations and how to ensure that AVs are safe and reliable.
- Regulations: There are no federal regulations governing the use of AVs on public roads. Each state has its own set of regulations, which can make it difficult for AV companies to operate in multiple states.
- Public acceptance: There is still some public skepticism about AVs. Some people are concerned about the safety of AVs, while others are concerned about the impact of AVs on jobs and the economy.
Despite these challenges, there is significant progress being made in the development of AVs. A number of companies are developing AV technology, and there are a number of AVs being tested on public roads. It is likely that AVs will become more common in the coming years, but it is not clear when they will be ready for widespread use.
Option a) is incorrect because AVs are not yet ready for widespread use on public roads. They are still in the testing phase.
Option c) is incorrect because AVs are not yet in the operational stage. They are still in the testing phase.
Option d) is incorrect because AVs are being considered by a number of companies and governments.
