3) More than 50% of hybrid owners, compared to 28% of conventional vehicle owners, indicated that the next new vehicle they acquire would probably or definitely be a PHEV [12]. 4) Nighttime charging was acceptable to over 80% of respondents [12]. 5) The vehicle acquisition decision is influenced more by what coworkers, friends, and neighbors drive than by dealers or promotional materials [12]. Finally, the perspective of Texas drivers (CenterPoint and CPS) was outlined in another EPRI report, Texas Plugs In: Houston and San Antonio Residents' Expectations of and Purchase Intentions for Plug-in Electric Vehicles [13]. The key findings of utility customers in those two Texan cites were as follows: 1) respondents believe that utilities should provide fast-charging availability and charging flexibility, but their willingness to pay lags behind what these facilities are likely to cost. The expressed willingness to pay for TablE 2. comparison of utility cost tests for EV infrastructure.
