I have an idea for those of us who want to buy now and upgrade later via software: a checkbox in the ordering screen that says "install this hardware option without software activation; $x for HW and $x for later SW activation". For instance, for the following options, I see this happening: Ludicrous Speed Upgrade (LSU): $10,000, or $2,500 to install HW now, and $8,000 for SW activation (it doesn't perform at Ludicrous levels until SW activation bought). Carbon Fiber Spoiler (CFS): $1,000, or $800 to install HW now and $250 for SW activation (it stays down until SW activation bought). Premium Interior and Lighting (PIL): $3,000, or $1,500 to install HW now and $1,650 for SW activation later (power liftgate, lighting, fog and cornering lights, door handle lights all don't turn on or operate until SW activation bought; the leather and headliners of course would be installed without needing to be activated). Smart Air Suspension (SAS): $2,500, or $2,000 to install HW now and $625 to fully activate all its software features (such as raise and lower, location awareness, etc.). On Model X, it would be mandatory to get fully SW activated SAS to get the tow hitch turned on (see below), but just tow hitch ability or both tow hitch ability and SAS could be ordered in the inactive state (for optional later activation). Ultra High Fidelity Sound (UHFS): $2,500, or $1,000 to install HW now and $1,625 to fully activate via SW later. The held-back items would be sound coming from the additional speakers and any other items that can easily be software disabled that are present on UHFS that aren't on standard sound. (Please, no graphic resampling to make it sound worse: the $1,000 HW should pay for something.) This would help people who want aftermarket sound, since this would allow more of the speakers and cables to be put in that are needed. Subzero Weather Package (SWP): $1,000, or $250 to install HW now and $800 to activate via software later. Literally none of it would work until activated. Rear Facing Seats (RFS): $3,000, or $250 for the factory to install the necessary HW for them to be retrofitted later, with the seats costing $3,000 to retrofit in later. Range Upgrade (RU): $3,000, or $1,500 for HW and $1,650 for SW activation later. The battery window of use would be artificially limited to the non-upgraded portion. Those who found later on that that 6% more range (15 EPA miles) actually makes a worthwhile difference in their life would go ahead and order the activation. Dual Motors: $5,000, or $500 for HW necessary to install later by Service Center and $4,750 for the rest of the HW and installation by the service center. On Model X: Option to go from 5 seats to 6 or 7 seats later: $500 Option to go from 6 seats to 7 seats later: $250 Go to 6 seats with above option from 5 seats: $2,650 Go to 7 seats with above option from 5 seats: $3,650 Go to 7 seats with any of above 6 seat installations that had additional seats option: $800 Premium Upgrades Package (PUP): $4,500, or $2,500 to install HW and $2,500 to software activate later; the following would be working if you get the $2,500 option: HEPA air filter system with dual activated carbon filters; leather; headliners. Self presenting door, ventilated seats, premium lighting (including fog lights) would all be installed but NOT WORKING until activated by software. Believe me, a lot of people would dive into this to get the air filter, then later think $2,500 for everything else would be pretty good. This whole option package can be rejiggled by Tesla to come up with better options pricing with later activation. Towing: $750, or $200 to install HW in factory and $600 for the hitch and software activation later. High Amperage Charger (HAC): $1,000, or $300 for the HW and $750 for activation later. What this means is that without SW activation, it would only charge at the 48A rate or lower. I think almost all the options should be installed close to cost for Tesla, so that they can both avoid losing money on this and make the lower capital costs as useful as possible for buyers making use of this activation later idea.
