Coffee Addict – That may very well be the reason for the heter, but I would delete the words (something common in Israel) as this may imply Motzi Shem Ra on both Am Yisrael and Eretz Yisrael.
Having lived in EY for many years, I actually have never seen that. If anyone is bothered by a lady walking in front of him, he can move to the side, and wait till all the women get on.
Personally, I usually try to move to the side and wait for the men to go on, so I am not walking in front of them. Once you are on the bus though, it can be impossible to avoid sometimes.
