Which is more frustrating, being stuck behind a street sweeper or a snow plow?

“Most definitely a snow plow because you can’t see anything and you have no idea how long you’re going to be behind that snow plow.”

“A snow plow because you have to turn on your windshield wipers.”

“Neither, I appreciate they’re doing their job.”

“A snow plow because of the debris and all the snow coming off the snow plow.”
