To the 2 cars (both older (+50) male drivers) who didn't want to let the female driver merge on the Expressway at the merge point, please look up what it means to "merge". It does't mean to back traffic up as far as possible for no good reason - even before the construction begins sign. To the transport truck drivers who like to start blocking the the passing lane before the Howard exit - shame on you, if I wasn't driving alone I would take pictures & forward them to your bosses, that is not your job to block traffic for no good reason. You guys make the traffic go way too slow, when there is so much more room to MERGE, I know you've heard this before - it's like a zipper & traffic moves much better. I have seen it be very effective while travelling by car in the USA, you may want to try it & see how much better traffic can be.
