Why not have faucets that you can turn on and off at will, but after N seconds of no "user input" they turn off automatically? Don't even make a super complicated faucet, just add an automatically operated valve to the pipe, and make it open quickly, but not instantly (so when you touch the faucet that was running at full blast you don't have an instant mess). Anything that involves a timer or a fixed water speed drives me nuts, and it's not because I like to waste water, at all. It's because I know how to use the thing, and might even want to use less than the fixed dose I'm offered.
