I'm thinking like making it a functional automated opening for pair of machine guns or a water squirt gun, take your pick! Just kidding.Yeah, that curvy stripe is pretty nice.
Also, I think they could have done something more unique with the grille. Why have a pretend radiator grille? Use that space to do something distinctive. Honestly, I don't see much similarity between the Solo and the Tesla other than the color, and the general shape dictated by the restraints of the functionality/regulations.
