I think I understand that driving faster increases drag because there’s more air pushing against your vehicle, but why is the drag for that distance greater at higher speeds? If a car is driving slower but across the same distance, wouldn’t the total impulse created by the drag be the same as going faster because it’s delivered over a greater time, even though it’s a smaller force at any given moment?

Depending on the cars gearing there comes a point where it takes more fuel to maintain the speed than it’s worth.
It’s not necessarily 55mph. My truck seems to level out around 85.
