Think the FIA specified a set height for the tip of the nose from the ground this year. Maybe expecting the noses to look something like the did in the 80's and early 90's.
Car designers have other ideas, they need airflow travelling under the car asap to get the car sucked onto the track, so it is unlikely you will see a full width nose be completely close to the track at the specified required height.
FIA isn't to blame for the look......the car designers are. Maybe the FIA should have gone further with the restrictions that had been set and demand the full width of the nose had to meet the front wing or something like that, then the crazy noses wouldn't exist.
Are the noses that low to help stop the cars riding over the top of another in the event of a crash? Safety reasons?
