>Compare to e.g. Hyundai with a 10-year/100k-mile powertrain and 5-year/60k-mile general in the USA.

Most cars are sold by the first owner between 30,000 and 60,000 miles. Hyundai's warranty is cut in half for the second owner, 5/50k powertrain and 2.5/30k general. There's nothing to cover, so it's basically free to put 10/100k in all of the commercials.

If it's basically free, then Fiat should offer it for the 500e, and I might consider buying one.
