[OT] Reminds me of something told to me by a mate who was doing 
mechanical engineering in the late 50s.  They were told that 
electronic controls and monitors on steam engines were not 
desirable because their failure rate was rather higher than the 
failure rate of steam engines.

I can only comment that, 45 years later and judging by the comments of 
those present-day colleagues who routinely "upgrade" their cars, the 
same precautionary principle should be applied to control systems of 
internal combustion engines today!
