Hi Gorger, sorry for the delay - I've been away.

I'm not sure I agree that it is street-side parking. There's a not-great mapillary image here https://www.mapillary.com/app/user/dezza?lat=54.053369355488&lng=-2.8008641940067&z=17&pKey=1443301276937769&focus=photo&x=0.19849821746880958&y=0.5797765189655096&zoom=1.235774252825336 - it's just a large area of gravel used as parking. I agree from reading around that parking aisle was incorrect.

My suggestion would be to leave as-is now, but I welcome guidance from a more seasoned mapper! :-)
