comment Why do showers have “hot” and “cold” knobs rather than “temperature” and “quantity” knobs?
@Scott The flow restrictor is a very small volume of water. I suppose there might be some people who want a dribble instead of a shower, but you are correct - if you really like a dribble of a shower, then you will have to be more careful adjusting your hot and cold valves to attain a specific volume and temperature. Or you spend the money to upgrade your fixture to a thermostatic mixing setup. In the US they are inexplicably still very expensive - 10 times the cost of the two valve non-thermostatic setup.

@DavidRicherby There is a flow restrictor in all new shower heads sold in the US. As long as that is in place, then the water volume is limited, and changing the knobs only changes the temperature, not the volume.

Most local government ordinances adopt new regulations slowly. So while this one entity may recommend these codes be adopted, the reality is that much of the US is still using building codes that are a decade or more old. Saying, 'They don't any more." is simply incorrect.

comment Why don’t we remove door handles and let doors open both ways (inwards, outwards)?
@SonDoLenh Correct, it is an engineering problem, which increases the cost of the door and decreases the security, safety, and sealing capacity of the door, which causes people to choose doors with possibly less-optimal user interfaces to meet their other goals.

comment Why do washing machines have windows?
If the power goes out during a wash cycle, and you aren't home to notice, how wet will you be if the machine is still full of water when you go to put your clothes in the dryer? On a top loading machine, not wet. On a front loading machine with a window, not wet. On a front loading machine with no window? Wet.
