When we headed out on those tight, twisty Sardinian two-lanes, the ones God built just for driving hard in a BMW, active steering felt, well . . . odd. A BMW's signature virtue is its road feel--live, precise, razor-sharp--yet at speed on these sinuous roads (roughly 40 to 70 mph), the system was constantly modifying the steering ratio, essentially keeping us guessing as to how tight we'd be taking the next turn. With a constantly changing steering response, we felt disconnected from the pavement in a very un-BMW way. These days, microelectronics allow near-limitless innovation. The greater question then becomes: Is innovation always an improvement?
