Obviously yes, If the value of BTC is around 6 digits like 100k USD then buying Tesla using BTC is not really a problem. However, tesla is no longer accepting BTC as a form of payment when you want to avail of their products so it's not really possible now.
If the price of Bitcoin reaches the price range you said it will be easy to buy Tesla vehicle and it was Tesla that stop the integration of Bitcoin as payment but that doesn't mean they can accept crypto credit cards.
