I removed FSD Dec 1st. Vined Dec 14th. Delivery Dec 27th. All cars come with FSD hardware its a download later. Only 10 percent of Xs purchased it through 2020. I can't imagine it would make a difference. They are just building and shipping.When I try and add FSD there is a button that says I acknowledge I can make no further changes to my vehicle... or something to that effect... so I don't have the guts to pull the trigger given 1) no idea it if will really help get my car any faster and 2) there is no way I want to pay for "FSD"... Maybe I should have more faith.... ?
