Allow me to explain, Gentle Reader.
This driver’s heading south on Masonic. See what s/he did? S/he “blocked the box” because of carelessness. You gotta look ahead to see if the intersection will clear by the time your light turns red. It’s Da Law. This is what I mean when I say too aggressive.
On the other hand, drivers heading north on Masonic sometimes want to turn left onto Fell. Sometimes these people don’t commit to making the turn by entering the intersection. Instead, they hang back by the crosswalk about 40 feet from where they should be, srlsy. Ppl, you gotta commit to the turn, you gotta be more aggressive.
