I think this is only a fair comparison if you disclose the waiting time between ordering the Tesla vs delivery.
The Audi, Volvo and Mercedes dealers may have been directing you at sub-optimal cars, but they were available to drive off the lot that day. If you're willing to wait 3 months, you can certainly order the latest Audi or Mercedes model with the exact specs and options you want. You can even pick it up at the factory in Germany and take it for a spin on the Autobahn.
