Investors urge tighter control over Elon Musk's leadership at Tesla.

A group of 17 Tesla investors, representing about $1.5 billion in shares, have written an open letter calling for CEO Elon Musk to be reined in, citing his many commitments to other companies like Twitter. The investors want a CEO that "dedicates adequate time and attention to the company" and for the board to overhaul its composition. They also expressed concerns about Tesla's ability to navigate the competitive EV market and other challenges. The company's stock slid after revealing aggressive price cuts eroded its profit margins in Q1.
