Tesla turns up charm ahead of investor vote on huge Musk pay plan

The company has mounted a social media campaign and even invited shareholders to enter a sweepstakes to win a tour of Tesla's Gigafactory in Texas, personally escorted by designer Franz von Holzhausen and Musk, on the eve of the annual meeting.

The contest winners ― 15 shareholders picked at random ― will also have reserved seats at the June 13 meeting, at which investors will also vote on a plan to shift Tesla's place of incorporation from Delaware to Texas.
