Explain the sentence:family travel has become the new family dinner.?

Being together in a car is as close to we get anymore to family closeness that was once attained at the nightly dinner table. Talking to each other, etc. HOWEVER, not since the invention of DVD players for vehicles, and MP3 players, etc. Everyone has earphones except the adults (usually)

Dinnertime used to be the time of day when every member of the family was there at once--children home from school, parents home from work. it was a time when the entire family could engage in conversation.
