Not a bad solution IMO. The chance of the user being able to change it, getting the ridiculous toque tire store lug nuts off, the wheel not being stuck to the hub, and the spare tire not being flat are pretty slim.
I was staying in a motel when a Canadian woman checked in who was traveling from New Brunswick to Quebec in her new BMW convertible.
She'd had a flat going through a construction site and had to wait nearly a week for the new tire to come in.
If my $60,000 sports car left me stranded because I couldn't get a tire, I wouldn't own it for very long.
