Getting back to original topic (I mean the misleading title one, not the actual content)
There is nothing wrong with …
Eating a bag of Potato Chips
Saying Tehillim (by heart only)
Singing out loud
Listening to torah tapes (or CDs)
Listening to your children
Paying attention to the road
and driving a car ..take it from me.
I can’t speak for the safety of some of the other things people try, like:
putting on makeup
watching TV on a dashboard screen
talking on a phone (especially handheld)
Eating messy food two-handedly
