Fixed or single speed

left foot braking is generally used by rally drivers who are of course often on different terrain. I've been lucky enough to try it myself (Red letter days). you may thinking of the "drifting" that the older cars used to do. They don't do that anymore because of technology and the fact its slower.

All F1 drivers these days left foot brake. Ther is no clutch on modern cars therefore one foot per pedal.

They brake whilst there is drive to the wheels as it is better/easier to control the vehicle whilst under drive, rather than coasting.

But this isn't about bikes or fg or ss. Arguing about F1 here seems silly.
