New York | Elon Musk has gutted the part of Tesla responsible for building electric vehicle charging stations, sowing uncertainty about the future of the largest and most reliable US charging network. The lay-offs of several hundred Tesla employees, which many of them posted about on social media on Tuesday, raised questions about deals that Mr Musk, Tesla’s CEO, struck with the leaders of General Motors, Ford Motor and other automakers last year allowing cars made by other companies to use Tesla Supercharger stations.
