They have potential, I like them.
Keep it simple, uncluttered shots are usually stronger.
The highway shot feels a bit rushed with the crooked horizon, and the gas station (?) one could benefit from a bit more exposure.
Also, they make sense as a set, especially the ones involving the abandoned cars or gas pumps.
Even if a bit cliched, you could make a nice gallery/exhibition on the subject, if you keep shooting that subject matter.
