notice that 1000$/LOC in a car with 1000000 units solds amounts to little more than 11$ (in the case of the article, IIRC: 11000 LOC), so economies of scale do make it perfectly feasable, I guess.
- kabouseng 13y agoYes, but it is not just the $ / LOC, it is also the time to market which influences the profitability of a product. But your point is taken, it might well be feasible to demand aerospace quality code from the automakers.
- WalterBright 13y agoImproving quality is not the solution. The issue is lack of a proper failsafe system - in this case, a STOP button that physically removes power from the ignition system. No amount of quality can guarantee the computer cannot fail.

- chas 13y agoIt is important to note here that that many automakers allegedly demand extremely high quality code from themselves. The MISRA C standard [1] is widely used as a guide for high quality embedded code in many industries and was developed by the Motor Industry Software Reliability Association.

- RogerL 13y agoIt's typically been my experience that (within limits) higher quality equals faster production. Can you imagine the debugging time they must burn with 11,000 global variables?
