They look stupid because the front wing, overal width of the car and rear wing are all out of proportion. If the cars went back to being 2 metres wide, and the rear wing width was increased by 20-30cm, they would look amazing. I'm worried about the direction the FIA seems to want to take F1 at the moment. There is talk in Autosport this week of "standardised major aero parts" i.e., FIA designed and built front wings, rear wings and diffusers. Along with the threat of standard engines and gearboxes, it seems the very ideas that make F1 what it is are under threat.
