Sadiq Khan has proposed a cap on the number of robotaxis operating in London to address safety concerns. This comes as companies such as Baidu are testing robotaxis in the city. Khan has also faced criticism for promoting a 'highest building competition' for developers and for allegedly covering up unlawful speeding fines. Despite these issues, the budget has allocated £10 billion for London's infrastructure projects, which Khan has confirmed. The mayor has been working on various projects to improve the city's infrastructure. Khan's initiatives include plans to develop new residential areas. He has also been focusing on improving air quality. These efforts aim to enhance the quality of life in London.
