The biggest leap of faith is with Commuter Cars’ business model, which could put you on a waiting list for years. Instead of raising money ahead of time and starting production, the company is focusing exclusively on building one vehicle at a time, and using the profits to create research and production capacity for the next vehicles. They are currently filling the first 10 orders—seven of them for the $150,000 model, which uses lithium batteries (from A123 Systems), and three for the $108,000 model using lead acid batteries. All future cars are “depending on funding” and pre-orders are fully refundable. By the way, the purchase price is for a “mostly assembled” kit, rather than a finished vehicle."
The 11 second pass in the Datsun was real impressive though.
