yeah, but there's no way to reach out for feedback or follow ups if not logged in. At this stage, we want loads of feedbacks and help genuine users plan their trips well, hence the login wall.

Well, as a "genuine" user, you'll never get so far as to get feedback since I'm (and likely others too) not going to bother with a tool that I can't even test its authenticity, correctness or usefulness of over known good individual routes for information. So if you want feedback; lower the friction. If it's useful, people will make accounts. E.g. too save searches and whatnot.
