Don't know how long they've been around, but this morning I saw two plain white SUV police cruisers, not the familiar black & white. Watched a Tesla driver get pulled over at Parker & Coit, didn't realize it was police until the lights flashed.
I've seen some pretty stealth things , but the Sheriff here in Llano County has a white Tahoe with clear reflective stickers that match the other patrol cars. Looks white from a distance and is completely noticeable when it's close.
I mean if you aren't breaking the law, you've got nothing to worry about. Perfectly fine with the nuts that are driving 90 weaving in and out of traffic on 75 getting pulled over
