I disagree in the short term (1 to 4 years). Tesla simply cannot make that many Model 3's which is one reason why this discussion is moot.
For all we know (and this is pure speculation), the reduced warranty (relative to Model S and X) may be part of their anti-selling strategy because there is no conceivable way Tesla could possibly meet the market demand for Model 3. They may intentionally be raising the price for Model 3 through various means (such as reduced warranty) in order to lessen demand. Again, just speculation but not an unreasonable guess.
I think EM promised a $35k base Model 3 and he just has to nickel and dime Model 3 owners to get the margins way up by way of forced PUP purchase for those with frigid winter climates and almost forced ESA purchase (which I'm going to purchase no matter what if I am getting a Model 3) to extend the warranty on the drive unit and distance on the battery. Those two options alone will move the $35k purchase to about $43-45k.
In my case, if the Model 3 ESA doesn't extend the warranty of the drive unit to eight years (from four) and the battery mileage to at least 150k miles (from 100) and if I miss the provincial EV incentive (June 2018 inflection point) because Tesla gave me a late 2018 delivery estimate, I might just take a wait and see approach and may go with a competitor when 50-60 kWh battery BEVs are made available (Leaf 2.0, Honda non-Clarity BEV, or even wait for a Toyota).
With no Right to Repair in the horizon, the cost of ownership post-warranty period for a Tesla can be significant and my household is not used to that and won't be taking our chances unless the ESA provides decent coverage. We finance our cars over 3-4 years but keep them for as long as the cost of repair / maintenance is insignificant (a few hundred here and there/annually, or even less). So far our Honda's and Toyota have been holding up fairly well.
I hold a first day reservation but don't mind the late 2018 delivery date because AWD deliveries are all post-June anyway. Even current Canadian Tesla owners have a late 2018 delivery estimate so I'm not complaining.
If Tesla were to open the Right to Repair, offer a decent ESA, and heated steering wheel, I will not hesitate to purchase a Model 3 SR AWD with PUP and I will not consider a competitor's offering but I doubt the Right to Repair is going to happen in the next two years.
