Wasteland: My items are infinitely upgraded

Today's dinner involved a lot of ferrying relatives around. I drove for five or six hours and made two trips to Changsha. I really don't have the energy to keep writing.

But when I got home at nine tonight, inspiration suddenly struck.

The apocalypse descends, and the protagonist, who drives for Didi, becomes bound to his vehicle. He can collect materials to constantly upgrade the vehicle, strengthening himself. He can also use the odometer to add skill points or something similar.

Then, he travels to various places to adventure, encountering all sorts of settlements, mutated humans, and mutated creatures along the way, accumulating resources, recruiting partners, or transporting supplies, etc.

During this time, he unravels the mysteries of the apocalypse and discovers the arrival of a new world and a new era.

It's very similar to the heavy truck war chariot stories from many years ago.

I feel like this idea has potential.
