The thousand selfish cars passing by symbolize:

In A Roadside Stand, the “thousand selfish cars” symbolize the indifference and apathy of the urban population towards the struggles of rural people. These cars, speeding past the roadside stand, represent the city dwellers who are preoccupied with their own lives and desires, paying no attention to the needs of the rural community. The term “selfish” emphasizes how these travelers are focused solely on their own convenience, without stopping to acknowledge or assist the rural people. The cars, as symbols of modernity and wealth, underscore the stark contrast between the prosperous city life and the marginalized rural existence.
