The local dealership had a similar deal when I brought my car in for major repairs (under warranty) and maintenance (not under warranty, I paid). They promised a free loaner of the latest model for a few days. I was bringing in a no-frills Camry-sized car.
When I arrived, the service manager came outside to help me. I got my two preschool kids out of the car and asked him to help grab the two car seats. He said, "Just a moment," and stepped back inside to talk to an assistant. Then he came back out and helped me unload the car seats and told me it would be a few minutes while they cleaned up the loaner car. I see the assistant drive a mid-luxury sedan around back. After about 15 minutes, the assistant comes back with a mid-sized SUV for me and sends me on my way.
(Though the jokes on them; I drove that car into the ground for five more years and then bought a Prius).
I love the loaner fleet at the San Jose Audi place; new TT/A4/Q5/A6. I think if you bring in an S or RS or A8 you get an A8. I asked what you got for an R8; apparently R8 gets fixed by their dedicated R8 guy in a few hours so they just pick it up from your home/drop it off with a flatbed.
Because they are standard here in Australia/NZ and IIRC the UK. Almost every major service center will loan you a car and provide a valet service. And the Annual Service Contract is typically thought of as a 'lock you in' scam to prevent you from getting cheaper servicing through third parties.
I don't really see a lot of innovation here. I would like to see the car notify Telsa of a specific component fault then they come out to house/work and fix it on the spot. Or do servicing at night time and on weekends.
I've never seen a non-dealership shop with a loaner car, but many have a shuttle. Of course, if you go to a cheap shop, they probably won't even have that.

He takes a typically irritating experience and makes it delightful.
Wish I could iterate the model S's industrial design... plastic nose bulb would be first on the chopping block.
