You can still hide, but I think they took away that aspect from a gameplay point of view, it doesn't seem like there will be crowds as in previous titles, so blending would be very difficult. Populations were spread out in Ancient Egypt, and likewise, other countries at the time. This sense of crowds didn't happen until the Renaissance, at least, when people became wealthier and could thus travel more often. 

I think it can be explained that Bayek, as a founder of the Brotherhood, might not have had training in social stealth especially since it probably wouldn't have been part of the regimen for Medjay who were warriors not assassins.
