It's definitely better, but the intersection treatment at Newbury & Mass leaves a lot to be desired. The rumblestrips they have on the ground by the corner on each side of the crosswalk don't seem to deter drivers at all--nearly everyone turning onto the highway just runs right over them...
FWIW: I've biked through every corner of Allston having lived there for several years, and never thought students were any worse than any other group in terms of walking in bike lanes. Issues were few and far between tbh.
