Increasing effective driving range per unit weight of battery over time is a valid Technology S-Curve. Increasing effective driving range per dollar cost of the battery over time is NOT a valid Technology S-Curve. [Fact] The following is a plausible explanation: Introducing a cost factor ("Per dollar cost of battery") can mask the effect of technological advance. For example, the company may have been able to find a cheaper and cheaper source of battery raw materials, say Lithium. That would make the curve look S-shaped even though no technological advance was achieved. True or False
