This looks like a ton of fun for kids (ok and adults). It’s the Chalk City Road Maker. Simply insert the included, or any standard size sidewalk chalk into the holders and you can easily draw perfect parallel lines to create “roads” on your driveway. There are two different sets of stencils (sold separately) to draw road signs and markers.
Make something that looks like this (yes that’s an adult riding an adult sized big wheel):
The other great thing about the road maker is that you don’t have to bend down to draw the roads. Great for kids of all ages. The Road Maker folds up for easy storage and transportability. Turn your driveway into an awesomeway.
