It is definitely an odd question when looked at generally. I can't think of another vehicle for which this would be a reasonable question. However, this is not an ordinary vehicle, and we're not on an ordinary forum.Maybe I'm not as well off as I'd like to be since I still can't think about purchasing multiple $35K+ cars at once.
Remember that many members here have paid $100k+ for one or more Teslas already. For many of us, our last vehicle was in more of a Model 3 price range - and the reason we stretched was for an exceedingly capable EV. Now we're faced with an EV that is 1/2 the price of the one(s) we've purchased - still get the EV drivetrain, still a Tesla. Maybe someone wants two for their household, or maybe they have grown children and want to give them. Or siblings, depending on the financial situation. If someone loves Tesla (or hates ICE vehicles) and has the means, it is reasonable to think they might give some to family members to get more Teslas on the road.
But yeah, "how many Honda Accords are you reserving" doesn't have the same ring..
