I wonder how accurate that number is. While science and engineering types might actually mean 99% when they say it, I find sales and marking folks often toss around "99%" when they simply mean "most." Of course the US 40kWh customers are still some months from production, so it is likely that few have finalized yet. Though, I expect reasonable demand for that car once it does enter production. People considering the 40 kWh battery car are probably less likely to give Tesla a $5000 zero interest loan.
