I'm more worried about the system that lumps ride and handling into one pot, when they are actually two factors meriting equal rating.
Rated separately, I would boost handling above 2, and might go so far as to drop ride down to 1. This would tend to hurt the smart, but it is what it is, a short wheelbase car with limited suspension throw.
Noise could easily be addressed by smart if only they would adopt the A-ten-uator rear mat. It cut the engine noise way down on our Passion coupe - money well spent.
