Tesla sales in Europe plunged for a fifth month in a row in May, a blow to investors who had hoped anger toward Elon Musk would have faded by now.

In February, the “Tesla Takedown” movement staged anti-Musk demonstrations at dealerships in the U.S. and Europe, and there was a spate of vandalism against individual vehicles and charging stations. Cybertrucks were seen on video being set on fire, while other vehicles had the word “Nazi” spray-painted or etched into their sides.

Elon Musk has reportedly fired Omead Afshar, a manufacturing executive overseeing Europe, where the company's sales are struggling.
