As Eric said I don't think we're rushing down a path to make any "rash" judgements on the topic, just healthy discussion of the pros & cons of both. As you point out the number of street driven cars is a primary reason it would be difficult to mandate anyway, but having seen the results of a couple of high speed crashes related to fluid loss and knowing how fast and how close we drive I think it is a highly relevant topic even if we have completely hijacked this thread for our own use.

To your points above, Red Line Water Wetter and similar products from Royal Purple, and others contain rust and corrosion inhibitors as well as lubricants for the pump and seals and are compatible with all the different metals used in various radiators which allows you to use water while addressing your concerns about corrosion and lubrication.

I can't personally see a downside of converting to water unless you forget to add "antifreeze" back for winter, but understand others may feel differently.

Regardless of which way folks decide to go with water vs coolant, one major area which would help minimize everyone's risk is preventative replacement of old lines, hoses and clamps rather than waiting for obvious signs of age or deterioration. I just replaced all the hoses and oil lines on my now 10 year old car even though there was no visible sign that they weren't serviceable. Just peace of mind.
