Suggested Changes
In a chase simulation, the following car only gets close enough to attempt a pass at 0 braking zones. Aim for 2-3 per lap.
The chasing car can't close the gap effectively. Longer straights before braking zones are key.
Bigger gaps between straight speed and corner speed create better racing and overtaking.
Combine tight hairpins with fast sweepers for a more engaging driving experience.
Sequences of corners with short straights between them (like Maggotts-Becketts) create memorable driving moments.
A wider speed range makes the track more exciting and tests more driver skill.
Too few or too many corners per km reduces the driving experience.

Detailed Analysis
Safety Analysis
Radius of your fastest corners (150+ km/h), plus banking and run-off coverage.
Whether each straight is long enough to brake for the corner that follows it.
Share of corners that tighten gradually rather than catching a driver by surprise.
Share of corners open enough (radius over 100 m) to see through.
Room to recover from a mistake without leaving the track.
Consider adding banking to high-speed corners for improved grip and safety
Overtaking Analysis
Simulates a car starting 1.5s behind. Slipstream on straights closes the gap; dirty air in corners opens it. Overtaking is possible when the gap drops below 0.5s at a braking zone.
No braking zones where the chaser gets close enough to attempt a pass.
The chaser can't close the gap — add longer straights to enable slipstream drafting
Higher speed differentials between straights and corners improve overtaking
Fun / Flow Analysis
Add more variety to corner radii — mix tight hairpins with fast sweepers
Link corners together with short straights to create rhythm sections
Increase the speed differential — add both slow-speed and high-speed sections
Aim for 2-7 corners per km for an engaging driving experience
