put the pedal to the metal
I need to hand in this assignment on Friday. So I will have to put the pedal to the metal.
A: Good morning, sir. Where would you like to go?
B: I need to be at the airport in 30 minutes.
A: The domestic or international terminal?
B: International, thanks.
A: I'll do my best, but the traffic is heavy at this time of the day. It's likely to take about 40 minutes.
B: You'd better step on it, then. We don't have a second to waste.
A: Sir, instead of taking the freeway, I can take a shortcut. I'll be able to put the pedal to the metal and get there much quicker.
B: Do whatever is necessary.
A: Okay, fasten your seat belt; this could be a little bit hairy.
