first time i "discovered" my transmission stick could be slapped to the left in drive, sport mode, merging on the freeway will never be the same

wife is starting to wonder why i swerve back and forth, once traffic slows.!! "just keepin the tires warm honey, just keepin them warm!"
(she puts face in hand and shakes her head!) I love her!! (and my wife!)
