Europe will type approve anything that proves it's safe and follows basic conventions. That will most likely include the Cybertruck, as the question really isn't "is this car a good idea?" - even bad products that nobody needs or wants get type approved, and Cybertruck really will not be the worst thing that happened to European roads.
Tesla knows very well how to get a US car type approved in EU with minimal adjustments. It was very curious to watch with previous models. They are quick, too.
