Elon Musk's Sleight of Hand

it seems to me that the model X still needs much more to become a self-driving taxi/rental (such as lidar or other sensors etc). if so, why would tesla include such complex features on the consumer version of the vehicle?

one answer might be that tesla intends to be able to upgrade _these_ model Xs to become self-driving taxis. maybe buyers of the vehicle would be given the option to rent it out for taxi services to generate revenue from their vehicles.
