There's no reason the default can't be changed. Ireland recently dropped the default speed limit on rural roads from 80km/h to 60km/h and regional from 100km/h to 80km/h. Councils can and do override the limits where appropriate, but in practice it requires an engineer's report which often doesn't, as the roads genuinely aren't suitable.

That would place the road above at a 37mi/h speed limit, which while still too fast for the conditions (it should be a 10 km/h or 6 mi/h road to support vulnerable road users) sends a much more reasonable message.
