I also take issue with the "no real benefit". More tire in the back means more traction for acceleration and braking. You also get better handling. This is why so many track cars run a staggered setup and why it comes stock from Tesla that way. I doubt they simply do it for looks since it likely decreases range.
Without getting into it again (grab a beverage and see: Dark Grey Turbines) I'd just say do some research on the subject.
If you dig deep, most track cars actually run a square setup so there's equal traction front to rear, so the fronts don't break free earlier than the rears. Staggered setups also don't provide increased forward traction, but rather slight increased lateral traction at the extreme ends of adhesion.
I stand behind my "no real benefit" statement.
You think Tesla would do all this for zero gain?
We've had very different experiences then. While I've heard people bragging about ridiculous things like the diameter of their wheels, I don't think I ever remember someone bragging about a staggered setup.Zero performance gain, yes, they would.
There are other gains I mentioned, mainly bragging rights and ego. That's why they did it. It sounds sexy and makes people feel like they have something special other people don't. It's called marketing.
