Define, compare, and contrast Robust Coexistence versus Robust Resilience (Adner & Kapoor -- "Right Tech, Wrong Time"). Why is electric car substitution for gasoline-fueled cars proving slower than Hybrid engine cars versus Gasoline-fueled only cars? Describe some specific issues that have led to this difference in substitution rates. What will it take if electric car substitution is going to accelerate from "Slowest" to "Gradual?"
