I look at demand as "a unique customer with a name has a binding contact in place and wants to take delivery in the future". The volume of demand (binding contracts) for Model X in August, for Europe, may be higher than Model S due to the production and shipment process of the X. Someone who is going to walk into a Tesla store this Saturday, take a test drive and then buy the car is "potential demand" right now and until they enter a binding contract, this demand is un-knowable. I believe many people utilize demand to mean many things including people who "might buy a Tesla by end of year, are looking into it and haven't yet decided". In the USA, demand may pick up slightly after next month's National Drive Electric Week events.

Thank you for posting your definition of demand. I like this definition, but it's not the definition that I use. My immediate reaction is that this seems like a good definition for demand, when your fundamental outlook is more short term - as this is the form of demand that is a direct translation into cars for the factory to build, now.
One weakness of this definition is that the way I read it, the 400,000ish model 3 reservations reflect no demand (lack of a binding contract). Of course, Model 3 can't be built in any case today, so its potential demand.
When I'm thinking about demand, my context is a long term investment perspective. I don't care about deliveries in the current quarter - I care about production. A weakness of this view is that run amok, it's easy to imagine a world where the factory is building cars that nobody wants. The strength is that in a production constrained environment, a unit produced is either delivered this quarter or next - there is only a minor difference in timing of receipt of cash (with quarter boundaries imposing arbitrary divisions with greater and lesser effect when adding up the total numbers). This quarter's growing production, is next quarter's baseline to grow from.
My definition of demand for a particular model is the number of annual orders for a model, when their is adequate supply over the course of the year to satisfy everybody's interest in the car AND when the neighboring segments contain a meaningful competitor / substitute. This will wax and wane with the overall economy. It is clearly influenced by the price the car is sold at (but supply and demand always include price in their functions). We might also think of this as the run rate.
For Model S, an important confounding factor is that there are no meaningful competitors in neighboring segments, where those neighboring segments include similar price but different body styling (think luxury SUVs), or same body styling and lower price (think BMW 5-series sedans). This confounding factor for understanding demand (or maybe run rate) is important because we know that Model S is pulling people that wouldn't otherwise be buying in this segment, into the segment specifically for Model S.
The only model I see today as a significant substitute that is drawing buyers away from Model S, is the Model X. And as the cars are made by the same company, this is hardly a problem for us as investors.
When Model 3 launches, I do expect that we'll see the first significant competitor drawing sales away from Model S (to Model 3). I also expect we'll see Model 3 pulling buyers from other segments further down market, and up to a Model 3. I don't know where the balance will be, but I expect the overall trend we see in Model S' segment, of buyers moving away from gas engine cars to Tesla will show up in these other segments.
As additional evidence this dynamic generalizes from Model S, I'm looking to see what happens with luxury SUV's as Model X hits significant production, the backlog gets cleared, and people can just order and take delivery of X.
The unfortunate consequence of my definition of demand, is that it's less tangible and specific than yours
@bonaire. And pretty literally means that in my view of things, I don't yet know what Model S demand is. Though the read from the more short term view of things is suggesting to me that we're pretty much there. That's a run rate of like 60 or 80k Model S per year? And I expect that will shrink when Model 3 launches.
What will the Model X run rate be once it's going?
