I remember when Honda went from a hidden steering arm (aligned with the wishbone) that they had in 2004-5 to the exposed steering arm, their cars sucked immediately. Now I know this was just a small factor among many but it seems that the 2009 Mac has also sucked and I think this could be a contributing factor. FWIW the Force India semi-clones are also slow.
