Tesla sales nosedived again in Germany last month even as electric vehicle sales rose strongly, data showed Tuesday, as German drivers voted with their wallets against billionaire owner Elon Musk.Some German Tesla drivers have put "I bought this before Elon went crazy" stickers on their vehicles and the backlash has also taken more forceful forms.

Demand for the U.S. automaker’s vehicles slid amid stronger competition from Europe and China and rising anger at Elon Musk’s political forays.

While Tesla's April sales numbers fell by nearly half, Germany saw a 53.5 percent increase in the total number of newly registered electric vehicles over the last year. While Tesla sales declined in Germany, sales for the Chinese EV company BYD's vehicles skyrocketed.
