Thread tax: You're in the passing lane, doing 5-10 over the speed limit, to pass a car going the limit. Someone rushes up on you 10 mph faster than you're going and is driving like a lunatic. Your plan is just to pass the car on your right by a few car lengths, take the right lane and let the maniac earn his speeding ticket. Then, as you try to graciously get out of the maniac's way, he tries to slalom between cars and zoom by you in the right lane causing a chaotic situation that is risky to all three vehicles.
Or the driver you're overtaking suddenly wakes up from his narcoleptic retard coma and speeds up to match your speed. Now you're trapped beside him in the passing lane with a maniac riding your bumper, and your only escape is going significantly faster than what you've determined is a safe speed.

I have this conversation about once a week at work:
Salesman: "My customer asked for this weird special request we've never done before. I need a price adder."
Me: "Okay, I'll get some quotes from our suppliers and get back to you."
Salesman: "How long will that take?"
Me: "Our main supplier for this kind of thing usually takes a couple days."
Salesman: "I can't wait that long. This job goes out to bid this afternoon."
Me: "Then decline to quote it."
Salesman: "This is an important job. Just give me a price."
Me: "Fine. Give me an hour to look into it."
Salesman: "I don't have an hour. I need time to put the quote together and-..."
Me: "Fine. Based on the retail costs from this thirty-second Google search, and adding in a 10% safety margin, I think it will take about $10,000."
Salesman: "That's too much. They aren't going to pay for it."
Me: "Then let me get some quotes or decline to bid."
Salesman: "How about $5000?"
Me: "We'll lose money."
[Salesman bids the job with a $5000 price adder anyway. The customer spends weeks sitting on this bid that could apparently not wait an hour. We sell the job and fail to make our desired profit.]
Salesman: "How come we lost money on that job? I thought you told me the adder was $5000!"
Utterly maddening.
