Hello.

I found some of your edits where you use designated instead of destination:
motor_vehicle	= designated means this sign: https://www.iamexpat.de/sites/default/files/sitefiles_2021-03/federal-highway-entrance.png (which doesn't exist in Luxembourg): C,2 sign (red circle: means restricted) 
By setting designated, you invite motorists to drive there.

Thank you for being careful. :-)
