I saw the unreal 5 engine demo the other day and it was showing the BMW digital twin and how they could select individual parts and remove them from the car. I thought how unreal would that be to be able to see exactly how you do mechanical work on your car before going out and doing it. This could be a huge learning advancement being able to visualize every singe component and digital tutorials on how to do it. Anyways check out the video I linked the time it shows the BMW https://youtu.be/WpnYqJsh-Dc?si=wHXz5A-pkOtGDDFV&t=392
