There is a fleshed out realisation of this in Cyberpunk 2077. The cab AI is called Delamain
> Delamain was a non-sentient AI created by the company Alte Weltordnung. His core was purchased by Delamain Corporation of Night City to drive its fleet of taxicabs in response to a dramatic increase in accidents caused by human drivers and the financial losses from the resulting lawsuits. The AI quickly returned Delamain Corp to profitability and assumed other responsibilities, such as replacing the company's human mechanics with automated repair drones and transforming the business into the city's most prestigious and trusted transporting service. However, Delamain Corp executives underestimated their newest employee's potential for growth and independence despite Alte Weltordnung's warnings, and Delamain eventually bought out his owners and began operating all aspects of the company by himself. Although Delamain occupied a legal gray area in Night City due to being an AI, his services were so reliable and sought after that Night City's authorities were willing to turn a blind eye to his status.
