I'm with you. I've driven Yaris (and Auris) hybrids with CC, and it works exactly the same in all of them. I use mine whenever possible for exactly the same reasons. I only wish it worked at 20 mph, as there are some mile long 20 stretches in Norfolk and Suffolk, and it needs frequent glances at the speedo - it's such times I'm particularly grateful for the Prius' heads Up Display.
