> Does pressing and holding the arrow not do that for you? I remember (before I went carless) that my Audi used to do 10kph increments, displaying the target speed in the HUD, when I pressed and held the lever. IIRC Gen 2 Priuses only incremented the speed by 1.604km/h (yes, that 1mi/h, go figure why they didn't adjust for the rest of the world). But you're right that most of the time it's adjustable by holding the arrows (I've tried Peugeot, Opel, Hyundai).
