Necessary for you and that's your choice but most Tesla buyers have showed they dont need a test drive
Like I said, if I just need a transportation, I could careless on a lot of things. However, I still need to know how the car drives, how I fit into the seat, how I can hold the goods from grocery stores and etc. Thus, the one to seal the deal was an overnight test drive on X on top of all the youtube videos I watched and assumptions I had from those.
People do want test drive. Taking orders online doesn't mean the deal has completed. BMW, Porsche and Audi are doing that now for their EVs and X7. You really think people will just wire the money to them without test driving a car costs over 6 figures?
