fwiw, from North East Fife (Scotland), it has been ('89/'90) "the Batmobile lost a wheel, and landed in the Tay", the Tay being the big volume river between Fife (the Scottie dog shaped bit on the East) n Dundee/Tayside (with the Tay having come via Perth etc)
I only know the Tay from the poem:

Hopefully I'll get to see it sometime.
Never heard that round there. I wouldn't count Dundee as "north east Scotland" either. Angus maybe. That's where they begin to sound like north easterners.
