Warning: TL;DR ahead...
@YusufT I agree with your principle and I was told a variant of this, but with more clarity and less "classist". During the delivery, I asked, point blank, the DS person to describe the service process of the car would being serviced at a service centre. Here's what I was told after the DS person consulted with some people (in the back).
A - if the car is safe to drive, I'm responsible for getting it to the service centre
B - if the car is not safe to drive, Tesla service will dispatch a flat-bed to take it to the nearest service centre (Montreal for Ottawa owners)
C - if I need a loaner car, I need to request it during, or after, the service call and the service centre will authorize a loaner from Enterprise
Point C has detail that wasn't explained as I was told that the Tesla people at the delivery event were NOT service people.
What I hope will be handled, transparently and with no cost to me, is a rental pickup from Enterprise in Ottawa, ON followed by a rental dropoff in Montreal, QC when I go to pick up the serviced vehicle. This is, by definition, a one-way, cross-province rental.
In any case, to get back to
@YusufT's comment, at no time was a Tesla loaner mentioned, BUT, when I asked if the service centre would be able to provide a Tesla loaner (I did not specify S or X or 3), I was told, "only if one is available". My guess is that there will rarely be one available. I asked this question, knowing that it does NOT apply to me. In order for Tesla to provide me (in Ottawa) with a Tesla loaner when my car is being serviced in Montreal... I don't see any logistics that would work with my current understanding of Tesla's service policies.
I knew at the time of order that there was no local service centre and I clarified the point of service handling before the "signature on the line and money handover" so I live with it and hope that Tesla opens a service centre soon in/around Ottawa.
