I was thinking it may have been more Milton then Andrea driving zombie bomb but a lot of people said the driver seemed to be woman.
I was thinking Milton because of governors asking him if he would take a bullet, Milton being nervous when talking to Andrea and looking at his watch, the driver didnt know how to shot a gun when running at Michone, Milton knew how to deal with walkers to get them loaded and lastly the zombie bomb showing up late with the governor looking surprised and pleased the bomb showed up at all. All that made me think Milton.
Now however I think it was probably just random town person female and it does not have much to do with the story.
