I get why more motors are faster and have more pulling power, and I get where the real Tesla fans really like more speed and more power and are willing to pay for it. But what i don't understand is what does the longer range option have to do with the all wheel drive and more motors, as they are only offered together. I would think that most average Joe truck driver (especially as a business owners) don't need, or even want the fastest version of a truck. Super fast acceleration, and a lot more moving parts is more of a liability than a benefit from a business stand point. Higher liability Insurance and more things to break... So I'm puzzled as to why Tesla isn't offering a longer range (bigger battery) in a single motor version. Is there some mechanical reason that the long range (500 miles) has to have 3 motors?
