Aibu to use a drop kerb to turn my car round

[StarofRoyal]

I’m afraid this is yet another school parking thread. School is on a long road so most people need to come in from one direction, turn around and go back the way they have come.
Today I turned my car round by reversing my back two wheels over the dropped curb access to someone’s house. They have gates across so I know for sure I didn’t access their property. As far as I’m aware whilst people are allowed to pave over the verge and have the curb dropped this does not make this part of the highway ‘theirs’.
The person living up the drive came out and ranted at me telling me not to do it. When I didn’t respond as she had hoped she walked all round my car (legally parked on the road) taking photos and then went into school, presumably to complain about me.
So am I unreasonable to think it is ok to turn my car around in this way?

She may have paid to have the kerb dropped, and depending where you live cost can run into £100's. Bad driving can and often does chip kerb stones, so if she has paid for it then I think she's right to complain.

Also, why shouldn't she live near a school? She may have lived there a lot longer than has been the fashion for parents to drive their offspring to school.

I'm interested in the idea that rubber tyres can chip curbstones.

What do you think they are for?

What's the point of this thread? Do you sincerely doubt whether you were BU?

The manoeuvre you're describing wouldn't bother me as it should be a few seconds tops on a clear road and you're on your way. The fact that she's had time to get to you in a huff suggests to me you're faffing about on her driveway? Are you impeding traffic and pedestrians while doing this?
