Car and Driver is dead wrong. It isn't "twitchy" over 90. We took ours up to 110 miles per hour... and it was smooth all the way. It actually felt like a hot rod. Obviously, this is a "don't try this at home" anecdote.

We didn't take it over 110. Typically that is where most cars have the auto shut off... and when it didn't shut off there we didn't want to take it up any higher for safety reasons... not that driving 110 miles per hour is the most sensible thing I've done this month.
