If a section of an interstate highway is reserved only for self-driving cars, there is potential for several business opportunities. Firstly, companies that manufacture autonomous vehicles could benefit from the increased demand for their products. As more people become interested in using self-driving cars, there will likely be an uptick in demand for these types of vehicles. Additionally, businesses that specialize in providing services to self-driving car owners could also see an increase in demand. For example, companies that offer regular maintenance and repair services for self-driving cars could be in high demand, as these vehicles will likely require specialized care. Another potential business opportunity is the development of new technologies and software that is specifically designed for use in self-driving cars. Companies like Google, which has already invested heavily in autonomous vehicle technology, could potentially develop new products and services to cater to this market. Overall, the potential business opportunities resulting from a section of the interstate highway reserved for self-driving cars are numerous. The key will be identifying areas of need and developing products and services that cater to those needs.
