I am consistantly amazed year after year with the creativity and abilities of F1 engineers. The top teams are constantly challenged by the F1 regulators throwing sticks in their spokes so to speak. If you watched the Singapore GP Vettle's mechanical advantage was obvious, while he's obviously a great driving talent I don't believe he's that much better than Alonso.
