Just an idea for the Model 3, steering by wire: With autopilot, your car is able to do the steering by itself. Why bother having a steering axis installed when everything could be done electronically? Just like in modern airplanes. Benefits: - Less weight, more range - Less mechanical parts that could fail - Faster build process of the car during production - You could have the vibrations of a bad road filtered out, more comfortable ride - Increase steering handling for maneuvering in the city, adjust response for the highway - left/right steering wheel setup is easier, cheaper - With a double redundant system, the steering wheel will be more reliable - Overall cost savings - The technology is out there, it exists in a reliable form. So the implementation would be low-risk What do you guys think?
