#9 Assortment of tyre colours employed in 2018 cut down drastically
In 2018, there were a total of 9 different colour combinations for tyres in F1. There were 7 color combinations for the dry tyre compounds - [1] Hypersoft (Pink) , [2] Ultrasoft (Purple), [3] Supersoft (Red), [4] Soft (Yellow) , [5] Medium (White), [6] Hard (Blue), [7] Super Hard (Orange); 1 intermediate compounds (Green) and Wet weather tyre compounds (Blue). The myriad of colours made things extremely complicated.
Keeping this in mind, the 2019 season will only have 3 combinations of tyres offered by Pirelli - [1] Soft tyres (Red), [2] Medium tyres compounds (Yellow) and [3] Hard tyres (White)
#8 Biometric gloves and stronger helmet
The newly incorporated biometric gloves have sensors which gauge and monitor the driver's pulse rate and blood oxygen levels. This facilitates rescue during crashes and is aimed at enhancing the safety aspect.
The new standardized helmets introduced this season have certain vital safety benefits including advanced ballistic protection and increased energy absorption. The front visor has been lowered to reduce the risk of injury from flying debris.
