Time to revive and detail the issue:
Both throttle and brake have a progressive 'mapping', at least since GTSport and it continues in GT7.
For example, although the readings in the controler menu show the correct pedal travel or force (in case of my loadcell brake), the way it translates in-game is not that linear. 50% throttle travel gives 25% pressure in-game. 75-100% trottle travel, translates to 50-100% pressure in-game.
This happens in a similar way regarding the brakes.
This makes driving a bit more difficult to modulate trail-braking, releasing the brakes will make your car rotate too agressivelly...
It's worst still with loadcell, making it jumpier when heel-and-toeing.
Managing traction is also more difficult due to the small travel - big effect that results from this progressive mapping.
I know it all tends to be less relevant the more you practice, but still, with the current physics, it makes even more sense to at least give players the option for a linear travel mapping for both throttle and brake.
FYI, I'm using a Fanatec CSL Elite with 3 pedal set (with 'standard' Load Cell brake setup to 50%)
