Estimates of the size of Saudi Arabia’s vehicle fleet in 2015 vary from as high as 18 million (Arab News 2014) to as low as 6.6 million (OICA 2019). This significant variation stems from the fact that the Kingdom does not operate a vehicle registration program that deletes vehicle registrations from the records after a vehicle is exported, destroyed in an accident, or depreciated by wear and tear (Algadhi, Mufti, and Malick 2002).

Rubal is a principal fellow at KAPSARC focused on understanding consumer decision making, in particular, consumer choice of energy-efficient technologies and mobility options under alternative technology and policy scenarios. Before joining KAPSARC, Rubal gained a Ph.D. at KAUST designing advanced carbon materials for energy and environmental applications, with a particular focus on energy storage, carbon capture, waste-water treatment, and hydrogen generation via solar water splitting. Prior to that, he worked at the University of Pennsylvania on a semiconductor industry-funded project, developing a continuum modeling framework for simulating the physics of micro defect formation in silicon crystals.
