Good idea. How about this:
"Thank you. I try, and don't always do as well as I did yesterday. I have a disability of the right hemisphere. The opposite of someone with dyslexia, I have excellent verbal skills but struggle greatly with accurate visual and spatial perception. Parking is a particular challenge. In a regular parking lot, it will typically take me up to three tries in order to park successfully. In the close confines of a parking garage however, I find this kind of maneuvering all but impossible, so I just have to do my best on the first try. Judging angles is very difficult for me, and I often wind up too far to one side. I do apologize for any inconvenience. Please keep in mind though, that although it is distressing for you when I park so close, I must struggle with this every hour of every day. I appreciate your understanding and tolerance."
