I have been enjoying distinctive tail light designs for a couple of years. BMWs tend to look like wings. Many Mercedes look like feathers. VWs look like tiered Ls on their backs with the long arms toward the center [or centre if you are a Brit]. Audis have a little arm to the "out" side. The list goes on. I especially enjoy directional that have a repeater on the side mirrors.
By the way, I agree that there are too many idiots out there who keep their brights on in traffic. Headlight design may be "improving" to give better vision to the drivers but is often blinding to oncoming drivers as well as making it hard to tell whether the brights are on or not.
