<p>MELBOURNE, Australia -- At the Melbourne Motor Show last week, Toyota unveiled a controversial concept car that would very closely monitor, and in some cases restrict, the actions of its driver -- including refusing to turn on.</p>
<p>To drive the sleek Toyota Sportivo, a driver would have to enter a memory card into its console to turn on the engine. Based on the driver's experience and driving record, the car adjusts its engine performance, cutting back for motorists with less experience or spotty driving records.</p>
