Steering Is Tight problems of the 2011 Toyota Corolla

Update!. On 11/25/11 I wrote: Nov 25, 2011 - the villages, FL - vehicle speed control this is a new car purchase (w/200 mi). At 60-75 mph (and noticeable also at slower speeds on other roads) on the freeway the car's steering wanders all over the road, it cannot stay on a straight line even if the steering wheel is not moved. T ---------------------------------------------------- update 3/2/12 - I have an update on the problem. The problem for me is not looseness or wandering from looseness it's an overly tight steering situation causing tracking fluctuations. . . Most cars have some slack or 'looseness' when driving straight at higher speeds. . . For safety. Humans breathe and move their bodies and heads all the time. This all translates to small natural movements in the arms and hands. If the steering at higher speeds is so tight that the least movement on the steering translates to wheel movement (imagine a go cart at 75 mph) , then while it's great at 30-45mph (for tight responsive steering) - it makes for an unmanageable struggle at higher speeds to control the steering. The car steering is reacting to the smallest movements. . . Think. . . Flying a slower cessna 172 where large steering movements cause slow turns, yet in a military jet a minute movement of the stick causes tight radical changes. Most humans are not jet pilots and we need some 'slack' at high speeds. . . Otherwise over-corrections could cause steering oscillation and loss of control (crash). Perhaps Toyota countered the 'looseness' complaints of 2009/2010 with overly tight steering in 2011. But Toyota guys, do you actually drive your cars? no real engineer would call the steering acceptable. It's really a serious problem. Just copy what BMW does. Their steering is tight, natural and yet totally controllable. Can I please have a new steering? please? for my wife's safety?.
