During Tesla’s Q2 earnings call on Wednesday, Elon Musk apologized to two Wall Street analysts for his behavior during the Q1 call.

Musk made waves on the May call by cutting off questions and calling them “boring” and “boneheaded,” which was followed by a drop in the automaker's shares the following day.

"These questions are so dry. They're killing me," he bemoaned in May.

This time, Musk said there was no excuse for bad manners and blamed his previous attitude on a lack of sleep due to the long hours he was working.

The analysts accepted his apologies.

Later, Musk suggested that Tesla’s future cars will also be polite, revealing that one of the biggest challenges he sees for the autonomous vehicles it’s working on is that they will be “easy to bully” by other cars and pedestrians getting in their way, as their programming will prioritize safety.
