Why dont washing machines have buzzers

Just about ever dryer I've seen has one, but the washing machines don't. Best thing I can come up with is "they" figure you will hear the washing machine stop after the spin cycle. More often than not, this isn't the case for me. So, my clothes sit there wadded up in the washing machine until I remember to check which is usually an hour or so after it's stopped. Occasionally, it's the following day. Guess I need to get a little timer stick to it and set each time, but this is one of those things that seems like it should have been addressed a long time ago. Weird.
