This drove me
batty on a daily basis back when we lived in Virginia, right off Interstate 95. I would invariably, about every week (so perhaps not on a daily basis, literally, but often enough) get behind some yahoo who would try to timidly merge into the 70-mph traffic by coming to an almost complete stop—forcing me and anyone else behind them to come to a near-stop, too. So dangerous!
I finally just started avoiding 95 if I could and taking side roads, even though that invariably took longer.
These days, I can't think of anything that bugs me on a daily basis.
