They change their order page all the time. If you custom order a new vehicle from them and it is produced and delivered after the point when they moved that out of the coming soon section, it will probably have that feature. However, if you ordered an inventory vehicle after looking at the options for ordering now, then you may have gotten one that was created before the site said that, and as most Tesla employees will even tell you they practically have "model months" you can hardly complain about last month's model not coming with this month's feature, especially while that feature will likely be delivered in an update. Further, and this would be your only legitimate reason to complain (outside of never getting the feature / unless the site was saying that before they could deliver it, which would take some research to prove one way or the other), if you ordered a new vehicle from the site when it said that, but they delivered an inventory model that happened to match your specifications, it might not have that update yet.
That was the exact order page I had when I ordered the car. My car was built after I ordered, ended production last night according to the My Tesla page.
