This is sort of odd for Republic. It seems that the E-170 guys are afraid to taxi around another aircraft, even with plenty of room. I have noticed this frequently in CLT even before these incidents. I don't think it is just certain crews, because I see it often. They could have over a hundred yards of room to go around someone, yet they decide to wait. With this over-cautiousness, it seems odd that within a week two Republic aircraft would be involved in this. Kind of ironic.
