Yeah, you can never walk in a perfectly straight line for long, but there's definitely a way to reduce having to move out of the way annoyingly often. Combined with looking up and planning ahead you'll be walking pretty efficiently through a crowd, because you won't be moving last second all the time, you'll adjust your path just slightly in advance. Has the added benefit of looking more confident and intentional so people will move to let you pass more frequently.
