All safety issues aside, this wave of dashboard dining may, quite likely, be unstoppable. Trays that fold down like those in passenger aircraft are on the drawing boards. My wife and I pull off the road, pick up our fast food, and get back on the highway, THEN the food is handed to me so that I don't have to take my eyes off the road. She holds the food or drinks while I eat, and after I'm finished, she eats. If she's driving, the roles are switched.
Same thing applies to using that cell phone.
When she drives, I talk. Safer that way. Let's try to keep the distractions to a minimum. Drive safe, and I'll see ya' down the road.
