introduce law to add bittering agents to antifreeze to save life

Some kinds of antifreeze using ethylene glycol taste sweet and can be attractive to animals - and small children.  Deaths occur every year from acute kidney failure caused by accidental poisoning through careless use of antifreeze and many screen washes, left in puddles or open containers; and moreover some sick individuals use this as a means to kill neighbours' pets in a horrible fashion.  By adding a bittering agent, the taste will no longer be attractive.
