Google map on iPhone is failing to find the way

I usually email driving directions to my email address and check the email from my iPhone to find my way while on the road. For some reason, these URLs are not working on Google maps in the iPhone even though they work fine on a regular browser… what gives?

This is an example. I’m sure the wonderkids at Google will figure it out eventually.
