Anne Brooks, of the Geography Department's Environmental Policy, Planning and Regulation group at the London School of Economics, has put together a brief survey on hybrid vehicles. Hybrid owners and non-owners alike are invited to participate. The information will be used in her ongoing dissertation research on the economics of hybrid electric vehicles.
As a self-selected survey, it's technically a scientific poll, but it should give her some insights into why people buy (or don't buy) hybrid cars. No personal information (other than opinions) is requested.
