Updates are delivered over your home internet connection, cell phone internet or both, routed to Toyota's G-BOOK telematics system, and should be fresh enough to warn you of a closed road or newly opened lane.
The system also has more or less the same book-inspired shape as Lenovo's U-series Ultrabooks, meaning when the notebook is closed, the top and bottom edges protrude ever so slightly beyond the sides, sort of like a hardcover shell cradling a spine full of pages.
