The issue is "niche". Niche is limited and will never be big. Niche is risky and volatile. Safety laws directly compete with Chaplin's motto. It will be very hard to sustain without giving up one of the following good traits about Lotus: lightness, steering feel, handling, low cost.
Funny thing is that gales mentions profitability with the Tesla roadster, so why not focus on electric? Detroit electric and Tesla has used Lotus platforms. Lightweight lithium phosphate batteries are lighter and safer. A hybrid should be considered.
