[Jak3] [high fps] Buggy acceleration slowed by high FPS

Describe the Bug

When accelerating in a buggy at high FPS (165/240), the buggy speeds up significantly slower than it would at 60fps.
This is especially obvious when reversing. I tried to attach a video of this occurring but the upload failed.

How To Reproduce

Be in a buggy on a flat-ish surface sitting still at 60fps
Hold either the Accelerate or Brake buttons
Observe normal acceleration/deceleration
Set fps to high value (165/240)
Repeat acceleration/brake step to observe significant decrease in acceleration speed, especially when reversing

Does this problem occur on original hardware or PCSX2?

Not needed, bug is obvious

Expected Behavior

Buggy's acceleration rate should match across all framerates versus real time.

Have you set the game to something other than 60fps?

Yes
