TX here, haven't had a front tag on my Camaro for 20 years. Been pulled over about a dozen times for it by State Troopers but never got a ticket and I am not drilling holes in my front bumper. I think they just use it to try and find other things to nail me on. I even stopped feigning ignorance several years ago. City cops have never even mentioned it.
Seems like changing the law comes up every couple months but nothing ever actually happens.
I checked a few months ago on the world wide interweb to see if I could find any local experience to one-tag driving in MD. I think it was a BMW forum, most recent post ~2014 or so, where one owner mentioned being stopped for something else, and ticketed $50 for the one tag. Another dude said it took about 2 months for them to stop him. Experience seems a bit fluid. Some NJ, I think, owners said that they've gone 30 years or more without displaying the front tag and no issues.
My plan is just to keep my car looking new enough and feign ignorance: "Oh yeah, I just got the car and received my tags last weekend. I was in the process of mounting the front tag--see, it's in the trunk! [I keep it there for just that purpose]--but the VW-supplied front mounting bracket didn't have bolt holes aligned with the MD tag, and I didn't have time to find a way to mount it without damaging the car...but I forgot about it all, unfortunately. Thank you very much for reminding me, kind officer sir and please don't shoot me!"
....well, that's changed a little bit because I did eventually mount it to the bracket and it sits in the trunk, almost ready to go. The bracket has clips on the bottom that allow it to grab the grill mesh, and the top is expected to be bolted in. I was fortunate that the dealer didn't go ahead and drill holes without permission first. ...I think that shop "got it," at least for the chuds that drive a GTI, like myself.
My plan has been to use some
3M dualock to tape the top of the plate bracket to the bumper, so that if I want/need to remove it, should be easy with a heat gun and no damage. ...the 2nd problem is that the top of the bracket isn't really flush on the back, and I think is too deep to affix one of the 3M strips so that it properly binds to the strip on the bumper. ...so now I'm stuck there. but whatever. I'm not mounting one of those ridiculous towhook mounts (or similar) for an off-center mount. I hate that.
