Why? Nations that formed OPEC were the major suppliers and therefore controlled petroleum production. Keeping it tight meant better prices for them. Going too far risked crippling buyers so a balance was necessary. That is how capitalism works.
Now that new ways of extracting oil have been found means the OPEC nations no longer control supply. As the newly accessible fossil fuel was released, it increased availability and reduced the price that could be gained. OPEC nations such as Saudi Arabia have kept up production and the flood of petrol has caused a price slump. OPEC has lost control of oil supply.
Benefit: Lower prices for the motorist.
Detriment: Car makers. Car manufacturing requires planning years ahead and I am sure their plans did not include crashing fuel prices. They are also being pushed in the US and Europe to lower CO2 emissions and higher fuel prices have been their ally in that. Consumers went for smaller, less polluting vehicles to save on fuel. The CO2 targets may have to be revisited or incentives (and disincentives) introduced.

So whether lower prices are good or not depends how you look at it. Our perspective will answer that for us.
