Google's always adding new tidbits to Google Now voice search, like that tweak to reminders we posted earlier today. According to ye olde Google Twitter account, you can also ask Google search about your rental car reservations.
Just casually ask Google search "when is my rental car reservation," and you'll get a card with the location, type of reservation, and dates. Just a quick, handy feature, and very much the kind of thing that would be super-useful on a smart watch, don't you think?
