There's a 4 mile 7% grade where my civic gets down to 22 mph in 5th gear. This has only been an issue the last time when a truck was riding my bumper. This is a 2 lane road that only has 2 brief passing lanes going up. Previous trips I either had more momentum going up, and more space to anyone behind me, or else might have put the car briefly in 4th gear.

The car is probably fine getting up in 5th gear, but the low speed could be a hazard when there happens to be other vehicles going up quite a bit faster. The speed limit is 50mph in this part. Considering this, at what speed would you put the car in 4th gear?

I could probably get away with only using 4th gear for the worst parts.
