I'll come clean
I went to visit my mum. Where she lives, the cat next door always sits on the drive and is very stubborn about moving.
When I turned up, there was the cat.
I began to reverse and it didn't move. Then I lost sight of it, and as I was looking from left to right to see if it had moved off the drive CRUNCH (no, it wasn't cat).
I hit a low wall.
I'm so annoyed with myself because despite 360 degree cameras and beeping galore, I must have totally zoned out and did not respond.
I was moving so slowly, not even 1 mph, so the damage is very insignificant, but as with all parts on modern vehicles, they can't withstand any form of impact.
I'm taking it in tomorrow for a quote to repair the damage.
