Do you know how to delete an account on the website of Tesla ?

Contact them and ask for the account to be removed.

I don’t know about the USA but they serve the EU so they will have to provide a way for you to exercise your right to be forgotten.
I emailed Tesla, but there's no response. Do you know the telephone number I should contact in Europe (the only phone numbers I found are Tesla Sales and Tesla Roadside Assistance)
