I've submitted a few of those to apple (from within the maps app) and they've been added within 24 hours. That may vary depending on the geographical region. But, yes, it's frustrating. I use Apple maps for the clean interface and option to get a sane and pleasant route overview. ("Hey Siri show overview" also works.)
