"Most accomplished" is a bit misleading.  Truth be told Danica Patrick is an average driver at best.  Her average finish in NASCAR's top-level series is 24th (bottom 40%).  In 180 starts she has very pedestrian stats - zero wins, zero top 5 finishes, 7 top 10s, and one pole.  She's led a grand total of 64 laps out of the 50575 laps she's completed (that's less than 1/10th of one percent of her total laps).  Her highest points finish is 24th (twice) all while driving for a team that has (not counting her stats) 21 wins, 116 Top 5s, 213 Top 10s and a NASCAR championship since she joined the series full-time.

I patiently await the day when a female driver who can contend for wins and championships comes along and makes us all forget about Danica.
