Abstract :
There can hardly be an engineer out there who didn??t follow the dramatic product recall of Toyota car models after the publicity surrounding a road accident in the United States in 2009. Mark Saylor ?? a veteran California Highway Patrol officer ?? was driving on a San Diego freeway when his Lexus ran out of control. The ensuing collision caused the deaths of all four passengers as well as a media frenzy, especially in the US. The phrase `sudden unintended acceleration?? entered the language overnight.
