Tesla is enhancing its voice control system, evolving from basic commands to a conversational assistant named Grok. This system supports various tasks such as navigation, phone calls, media search, and vehicle commands. Recent updates to the Model Y owner's manual indicate that text messaging will be a forthcoming feature, allowing users to ask Grok to send text messages. Grok has expanded its reach from the U.S. to several other countries and is designed to manage vehicle operations while maintaining driver focus. Future developments may include Grok Bot integration and control over Full Self-Driving capabilities. The exact timeline for text messaging activation remains uncertain, but it is expected to be part of an upcoming over-the-air update.
