Imagine the scene (we have to - we don't know how to drive).
You're in a car, on a dual carriageway, and you want to get over into the lane to your right. Only one of the cars in that lane won't let you.
What do you do?
Well, if you're the driver in the video above, you wait for your moment... and then get your own back in spectacular fashion.
Honestly, how did we amuse ourselves in the days before dashcams? Oh yes, with cat videos. That's how.
