Is it 'your' road, or a public road that you live on?
I used to live on a public road opposite a school and thought like you, so long as they leave enough space for me to get in and out the drive who cares.
We have a private road next door to the DCs school. Its basically a wide gravel road. Usually full of holes filled with stagnant water.
The upkeep of the road is entirely at the cost of the residents.
The heavy traffic on the road is causing obvious damage. It can be seen as the worst damage is at the end of the road closest to the school, where parents park, turn around (multipoint turns as its a narrow private road), reverse in to stop and start as they drop kids off. The end furthest from the school where it is difficult to turn looks immaculate. It will cost the residents a fortune to fix the damage. The majority of which is not caused by their reasonable use of their own road but the heavy use of multiple cars briefly stopping and starting)
I feel for them, the school sends out requests to not use the road. The requests are ignored.
I am lucky I can walk my kids to school. I would hate to have to do the drop off madness every day. But it is still unreasonable to use private land for drop off unless you plan to pay for the damage being caused.
