A new national survey has found that 15% of Americans eat lunch in their cars. This was more than the percentage of people that eat lunch in restaurants -- which was 14%. The study also found 35% of poll respondents indicated that needing to eat lunch while doing something else, like driving or working, is a challenge to eating a healthy meal. If you have seen the lines at the fast food drive-thrus and you have noticed the people around you eating in their cars (sometimes while driving) then this survey is probably not a big surprise to you.
