Following the Russia invasion on Ukraine an oil supply shock is expected and what is worse there may be no supply increase from OPEC+ . A way out is to cut the demand as advised by IEA. The proposed steps are quick-wins: easy to implement and reverse while having measurable and significant impact. The overall impact should balance the supply gap.
Quantitative estimates can be backed with empirical or even statistical evidence. A good example is the speed reduction, as recent research advances demonstrate quantitatively what drivers learn by experience: fuel consumption considerably increases with speed beyond a turning point. Turning this statement around: you can likely save lots of petrol driving at a lower speed. The study of He at al. finds cubic approximations fit well and enables several optimisation considerations for various groups of car users.
