I thought the vast majority are OCR and the humans are for the ones it fails at. Regardless, all you have to do is tell people, say at the post office, that if they type the address and cut it out and tape it on, the mail will get there faster. Alternatively they could use a label maker to print out the address and then affix it to the envelope. I bet people still writing address labels by hand probably mostly don't know that there's a speedup for fast machine legibility.
