I drive roughly 80 miles a day, which is why I bought the Niro HEV. I'm used to being able to adjust the cruise control on the highway by either speeding up or slowing down. Seems basic. With he Niro I set it at say 72, it immediately slows to 70, then may recover and got to 73. If I want to speed up from say 71 to 73, I push the lever up (+) and it responds slowly, but then doesn't stay there. Maybe because it is such a low powered vehicle, it doesn't stay at a set speed. My previous VW TDi was easy to drive using just the cruise control.
