Post Google Map Throws Hundreds of Validation Errors

it will because of the API google maps uses. it has strings like:

?map=7274hdfgy&tile=sdojwskj&stuff=od839d

All the “&”‘s will not validate under a XHTML doctype that WordPress uses. The doctype wants these to be written as “& amp;“. You can’t do that because the script will fail. So although the validator says it doesn’t validate you need to pay attention to the fact that it’s a script not a layout/content issue.

It’s not really an issue.
