I always imagined this could happen. My dreams coming true. And today I learned...my dreams have already come true!
If you're like me, a stickler for the rules of etiquette on the road, then you will love this as much as me!
Here's an example. You're being cut off on the road. Not only does it disrupt your speed on the road, but it affect the other people on the road behind you. Now you've had a chance to make your retaliatory move and cut back in front of that person. But do they know why you're cutting in front of them? Are they just oblivious? It's highly likely.
So...here comes what might be one of the best inventions for drivers of all time. Your very own digital sign. You can actually let the jerk behind you know that they're...well...a jerk!
