Here’s what we know about the Tesla event so far. The launch will include a limited number of Tesla vehicles debuting in Austin on June 22. The initial rides will be in the Model Y and not the CyberCab that was unveiled in October.

In a letter signed Wednesday, a group of Democratic lawmakers asked Tesla to delay the launch until Sept. 1, when new safety guidelines for autonomous vehicles go into effect.

Tesla will launch its robotaxi service in Austin on 22 June with 10 cars, despite calls from Texas lawmakers to delay until September.
