I think the real observation here is not so much that print is more legible than cursive, but rather that most people actually suck at handwriting. That can be solved in two ways: get them to practice it with an aim towards improving legibility (good luck), or tell them to give up and just type everything (easier). People who adhere to a particular form, whether it's a form of print or cursive, and do it consistently and with superior execution, have very legible handwriting.
