I know major oil pipelines do exists either underground or under the seabed. However, these usually move crude/unrefined oil from refinery to refinery. Yet we don't have refined petroleum or gas directly piped from refinery to the gas station? I mean we have done it with electricity, water, sewage, stormwater and piped LPG gas (for cooking), why do we still see petrol takers plying the roads to top up gas stations that you go to top up your car?
NOTE: I understand this is easier to achieve in big cities and Urban areas rather than laying pipework for rural areas. But I so not yet have concrete info this is implemented in long term gas stations located in the cities.
