Sorry for being explicit, but this is a silly discussion. The population of most oil-rich Muslim countries is not poor, those without oil (Egypt, Syria, Jordan, Pakistan) or with major wars behind them (Iraq, Afghanistan, less so Iran) are really poor. To stop driving cars won't affect the regimes of the poor countries, and (unless oil production is throttled severely so that other customers buy less for much more) won't make the subsidized population of the oil-rich ones richer. On the other hand, stopping driving cars will help Europe to get closer to energy independence, and reduce greenhouse gas emissions. (I already don't have a car.)
