Not sure if bought or DIYd but I seen one of the LED things, it was extra funny because it was a Canadian and they had it in English and French.

It was something like this https://www.amazon.com/Leadleds-Scrolling-Message-Display-Controller/dp/B00NQ1V9R8

Get an illuminated sign for your back window that you can program a message into like "wanker", "twat" or "keep your distance" and turn it on when they tailgate.

You sir, are in luck

$50 on amazon

Had this one. It works. People were VERY curious where I got it from.

There are aftermarket ones you can install yourself! I've always wanted one on my own car just to say something random.

These are available and have been for a while. Don't see them much though. Quick search

I thought it would be fun to display what song you're currently listening to.

Those exist
