If a $100 investment is truly all that's needed to convert a gasoline-fueled vehicle into a flex-fueled one, then they aren't truly locked in all that tightly for their 15-year lifespan.
The State of California could even pass a requirement that all new gasoline cars sold after i.e. 2016 be flex-fuel capable, and after i.e. 2018 that all cars on the road be converted to accept flex-fuel if possible/reasonable. Start collecting signatures for a petition to get on the 2014 ballot, and maybe we can get that first step accomplished.
