But now mobile diners can scarf down snacks without worry, thanks to "The Drib," an adult bib that has you covered -- from your neck down to your thighs, actually.
The Drib, which resembles a cross between a bib and an apron, is made out of absorbent cotton lined with a special water-resistant material.
Co-creator Jill Clontz told AOL News that it's weighted down in the shoulders with thin, recycled tire pieces so that it sits on the wearer without slipping, eliminating the chances of messy accidents while eating and drinking in the car. It also features a pocket at the bottom specifically to catch any wayward crumbs, chunks or liquids.
"I've never had anything leak through it. Not even the time I spilled a whole cup of clam chowder on myself in the car. Instead of getting all over the place, most of the soup went straight into the pocket," Clontz said.
Clontz, who works for the Redken division of L'Oreal, said she created the product with equally busy friend Donna Ballinger after having one too many coffee stains wind up on her work clothes.
"The main idea was to make something that would catch any spills on the road so my outfit wouldn't be a mess by the time I got to work. Something that wouldn't cause drivers to have to look away from the road if they spilled," Clontz said.
But the plan took some time to convert into a real, functioning product.
"At first I'd just get a towel and throw it over myself in the car, but it kept sliding around. Stuff would seep through it and I would have lint all over me," Clontz said.
"Once we decided on The Drib, it was so much better. If my coffee top pops off in the car now, who cares? The Drib catches it and then you can throw it in the wash."
Although it is, essentially, a bib for grown-ups, Clontz insisted it's not as degrading as it sounds because it doesn't tie in the back.
Plus, as she noted, it really can't get more degrading than showing up at the office with a coffee-stained tie or to an important business meeting with a blouse covered in ketchup from a fast-food burger gone wrong.
And Clontz says The Drib has multiple other uses. According to her, it can be draped over the body at sporting events while eating messy foods like nachos and hot dogs, worn while cooking or used on kids at any time, whether they're snacking at home or on the go.
"If you're cold in the car, throw it over your lap. If you need a pillow while traveling, fold it up and use it as one," she added.
Most importantly, though, Clontz said The Drib, which sells for $19.95, represents total and "instant freedom" while eating on the road.
She said her favorite use for The Drib is while ordering curbside service at Applebee's.
Though you may think The Drib is novel, it's not the first of its kind.
A few years ago, travel-savvy salesman Dan Steel of Ambler, Pa., invented the "Carbib," also an adult bib for folks who constantly dine while driving.
Steel told AOL News he still sells "a handful" of Carbibs each week (the adult size goes for $15.95) but dreams of eventually teaming up with a fast-food franchise to really get his product off the ground.
He's already tried to pitch the drive-through-friendly product to McDonald's as "The McBib," but hasn't had much luck.
"I'm not legally allowed to use the McBib trademark," he explained. "But I still think there's an opportunity out there with another fast-food chain, a deli or even a convenience store."
"The kids' size holds a small or medium french fry [carton], and the adult size hold a large or extra-large. It eliminates a lot of the distraction and danger that comes from having to reach around the car to find your fries," he added.
If the fast-food merger doesn't work out, Steel plans to possibly market his product to nursing homes, since the current assortment of adult bibs in the elderly health care field seem to be somewhat lacking in both style and comfort.
Whichever model suits you best, you're finally free to pig out on the road and reach your destination without looking like you came from a pig sty.
