Tesla told U.S. regulators that its answers to questions on the safety of its robotaxi deployment in Texas are confidential business information and should not be made public, according to a letter released on Monday.

A group of social media influencers and Tesla investors were invited to participate in the Robotaxi trial, with many posting about their experiences online. Passengers were accompanied by a Tesla employee in the front passenger seat to oversee the ride and intervene if necessary.
