The discussion centers around the Chevrolet Volt and the current state of hybrid and electric vehicles. There's a noticeable increase in advertising for the Volt and electric filling stations, indicating a growing market presence. However, potential buyers express hesitance due to high costs, with some considering regular hybrids instead. Concerns about the value proposition of hybrids are raised, especially when comparing them to older, more efficient models like the VW Rabbit Diesel, which offered better fuel economy and practicality. Additionally, the Aptera is mentioned as a promising vehicle with a potential for over 100 mpg, highlighting ongoing interest in highly efficient transportation options.
