Every action has an equal and opposite reaction, and every reaction prompts an appropriate response from the Tesla's computers. What's amazing about the experience is that without the torque interruptions necessitated by shifting or the distraction of a howling engine, you have the space in your mind to pick out just what's going on. It's almost as if time slows down. And yet, it all doesn't feel as digital as some heavily computerized super-sedans of recent years. The machine is doing real, mechanical work, and it's a pleasure and a marvel to experience it.
