[Cars] How did the 10 or so local cars of Radiator Springs stay in business after the Interstate was constructed?

From my understanding, the Interstate bypassed the town, eventually removing it from the map and cutting the average amount of customers to almost 0. So how did Flo and Ramon and Luigi and Guido and Mater and everyone else stay alive if they barely have any income?

Well, they all own their properties outright, so no rent or mortgage or anything like that.  And if they've gone so far as to take them off the map, one assumes that the tax-car isn't stopping by to collect anytime soon.  All told their expenses will be very low.  Add to this the communal nature of their town, and it doesn't take much cash flow to keep things going.  

Between natural resources around, and one or two of the residents occasionally going into the bigger city to sell stuff, they get by.
