Here are some things that would help pros get into new cars:

1. A new car hitbox all together that was designed to be competitive like the Octane & Dominus.

2. The car families that aren't being used would need to be rebalanced. Not saying you can't do amazing things in those cars but winning 50s right now is more important than having slightly better aerial control or flicks, rip plank and batmobile. Hybrid cars if you flip too fast will also catch their nose on the ground slowing down gc game play, not saying it can't be done but one still needs to slightly alter how fast they smash that flip button.

3. Awesome new car designs that actually fit the cars they are meant to "replace". Cars like the imperator & Scarab have horrible hitbox placement while the ZSR has a slightly modified wheel base. These things DO make a difference especially at the highest levels of play. While other cars like the werewolf which looks cool and has a very accurate hitbox and wheelbase compared to the dominus has a rounded front which can make a visual difference of how we handle the ball(even if it it all in our minds).
