There are plenty of ways to plan a trip, but few that offer up a listing of the sights and stores you'll pass along the way. OnTheWay does just that, giving you not just an overview of the map, but a guide to what you'll pass.
Currently, it's still in its starting stages and shows mostly petrol stations and restaurants, but if you or someone in the car is a picky eater, it might help you decide where the best the eating option is.
More interesting is the selection of roadside attractions, museums and parks. Here you'll be able to get a quick glimpse at the towns you'll pass through and the attractions they have. Perhaps you'll find a ventriloquist museum worth popping into, or a national park side route you weren't aware of. Unfortunately, there's no filter option at the moment, so once you enter your route, you'll have to look through a few pages of nonsense in order to find what you're looking for. The database of oddities isn't as massive as say, Atlas Obscura, but it's a start. If nothing else it will better prepare you for what you'll see on the road and you'll be able to look up reviews of the World's Largest Groundhog before wasting time stopping in.
