Can anyone think of any good reasons why Tesla Motors should not give customers buying the S Standard an option to pay some additional dollars to get upgraded Sport handling with many of the same parts, changes they've included with the P85 Plus option? I believe that many buying non performance MS would (after comparison driving an S85+ against S85) elect to pay extra for a handling upgrade like this. I don't think they need to make that enhanced handling 100% of P85+, just much of the upgrade for a price that makes sense for a Standard. I'm not clear on how critical to great handling the 21 inch wheels are. My guess is that Tesla could offer this option in two flavors. One using 19 inch at a lower extra cost and another with less compromised with the 21 inch, at higher cost.
