Thanks for reminding me about electric cars -- they are an obvious
use-case.  If I got an electric car now, all the power would be
charged at the highest tier rate (since they keep raising rates
by adding tiers) almost every month.

But if there was a special low rate for recharging electric
cars, then it might make economic sense.  A smart meter
could support this sort of social engineering much better
than what we have now.
