Eating may well be more dangerous, as could be doing lipstick, reading a newpaper etc. I think the scarey thing is how many people you see on a mobile every day while driving. As a Motorbike rider I can't do either, but i do get a good view into vehicles, and I see, probably, five times more people using mobiles while driving than eating.
I cannot tell you how many people using mobiles veer across roads and don't check their mirrors blind spots when manouvering, but I avoid one doing this every day, 5 days a week, 52 weeks a year.
I think it's not simply what's dangerous, but how many people do it without thinking. A recent poll in the UK suggested that 90% of people questioned thought that using a mobile whilst driving was dangerous but only, approximately, 45% of those people thought they were dangerous using a mobile while driving. As they say, ignorance is bliss...
