Tesla will have a ton of options. Only they know which demand levers they will pull if they need some more customers.
First of all, after the first of they year they will all be exhausted and totally out of CPO, inventory and demos. They are pulling out all the stops currently to get every single car delivered before EOY. Friend just ordered her Model 3 dual motor today and she has already been matched up with exactly what she wanted. Super happy to be getting it before Christmas.
After the first of the year they will regroup. Take a look at how orders are coming in and their production capabilities. Will check to see how many batterys they can source and make their plans.
First they will restock the showrooms with new demos and service centers with loaners. They will build up their inventory as they are opening up several new international markets. Will begin to produce Right Hand Drive vehicle for several countries.
About then they should begin to see another rush of orders, for people wanting the get the $3,750 tax credits before June 30th.
Also about time to release the long awaited +/- $35,000 basic package Model 3. Believe that will bring in another flood of orders.
When they get their FUD option going, I believe that many early customers might be tempted to trade in their older Teslas to the the newer computers and the easy drive option.
If demand is lacking they can always add free supercharging, upgraded wheels, premium interior for the price of a standard interior, upgrades to a larger battery or a premium paint color for no extra charge, things like that.
By then they should have begun to take deposits for the Model Y CUV, and perhaps Pickup.
Last thing they will want to do is lower their selling prices.
