FYI not ALL drive by wire cars are soft like that. Actually none of the other drive by wire cars I've driven have felt as soft as the Versa.Welcome to the world of drive by wire throttle...every new car has it fyi so that soft pedal feel is not limited to the note
OP: Aside from getting used to it, easiest solution is to get cruise control. There is a company in the states that makes a cruise system for pretty much any drive by wire car, including the Versa. I put one in mine. The install was so easy a monkey could have done it and it worked pretty well.
