It feels like aeons have passed since we were nestled in the Barcelona media centre, mouths agape with surprise as Lewis Hamilton pulled the steering wheel of his box-fresh Mercedes W11 towards him.
As he did so while exiting the final corner, the front wheels pointed inwards by a few degrees, before returning to their regular position as Hamilton pushed the wheel back in. What was known within Mercedes' own circles as DAS - or dual-axis steering - gave the team a way to run more toe out in the corners to boost cornering grip, while being able to turn the toe angle in to limit drag on the straights.
Who says Formula 1 is too restrictive? As the Nobel Prize-winning economist Bengt Holmstrom once opined: "The thinking is that creativity springs from freedom. That's a fundamental misunderstanding. Creativity is born from challenges, limitations and questions."
