In a report on the IU study from The Detroit News, we find that some 95 percent of survey takers didn't know about incentives from state and local governments, including both rebates and incentives. Seventy-five percent of respondents were unclear about the fuel and maintenance cost savings that EVs could offer. What's more, of 758 persons that lived in areas that offer subsidies for home charging equipment, a paltry 2 people were aware that the financial aid existed.
With the apparent knowledge levels so low, it's understandable the immediate prospects for wider spread EV sales are not great. Said report co-author John D. Graham to The Detroit News, "What should be particularly troubling for plug-in electric vehicle proponents and manufacturers is that the respondents to our survey live in major urban areas, the places where PEVs make the most sense due to daily travel patterns."
