It’s not a bad trade off when you give the average person 100 bucks in juice a year and entices them to give you 10,000 upfront for a capital infusion.
People make highly irrational decisions to get free things.
I don't think that's actually how it works. Usually the decision is made first, and the justifications second.
I think most can agree that it's really hard to rationally justify $10K more for a P3D especially as far as we've been told the hardware is identical. The vast majority of the cost to Tesla is likely additional wear due to the increase in power, and stresses on parts. So they likely estimated more warranty cost for a P3D.
I personally don't see any rational decision for the P3D unless someone wants to take it the track. For track purposes I can totally see it fitting what a person might want. It has a track mode, and the initial reports say it tracks pretty good. It still slows down a bit after a few laps, but it looks pretty solid overall.
As a multi-purpose vehicle it helps to have other justification.
The free unlimited supercharging is a good adder. Sure it's no more than $100 or $200 a year. More importantly it's attached to the owner, and not the vehicle. So it won't help resale like it does for grandfathered Model S/X's like I have. I'm absolutely going to use it as a selling point when I do sell my Model S. The free supercharging means more the cheaper the vehicle especially with people who have large commutes.
Probably the biggest justification of the P3D is exclusivity. People simply do not like owning the exact same thing as hundreds of thousands of other people. Or at least I don't.
So how does on differentiate there's versus all the others? Wraps? Body kits? Power? If I do go through getting the Model 3 I'll likely do all of them.
