I take it as an easy up-sell, "would you like to Performance-ize that for $2,000?" Some will say yes, some will say no thank you.Yes it is. (I didnt say P3D-) The P3D is 7k more. The off-menu P3D- is only 2k more currently, but I would expect that option to disappear soon because it is sabotaging the sales of the P3D and LR AWD. It makes no sense to pay 5k more for wheels that are arguably uglier and slightly bigger brakes. It also makes no sense to buy a LR AWD if you can get a P3D- for only 2k more.
It takes them, what, 5 minutes to upload the software for the faster acceleration? Totally worth it for both Tesla and the people that want it.
