Sorry, I need to create new post here because I can't edit OP as 1st post. ;)

The yawrate means the angular speed. :)


-- Spa, Belgium
turn 10
G-Force avg
5.5 - Hamilton Q2 - 2018


-- Barcelona, Spain
turn 9
4.6 - Hamilton pole Q3 - 2018 on track repaved
4.3 - Alonso pole Q3 - 2006
4.7 - Bottas pole Q3 = Vettel P3 Q3 - 2019


-- Melbourne, Australia
turn 14
2.4 - Villeneuve pole - 1997
4.4 - Hamilton pole Q3 - 2017
4.8 - Verstappen P4 Q3 - 2018
4.7 - Hamilton pole Q3 - 2019


-- Siverstone, UK ("F1GP1" game but turn 1 projected wasn't real in 1991)
turn 1
6.1 - I played to pilot by 1991 car on computer


-- Hungaroring, Hungary
turn 4 (until 2002) and 5 (since 2003)
5.0 - Vettel pole Q3 - 2017

Yawrate is the sum of the trajectory heading velocity plus the sideslip velocity and the sideslip velocity has higher peaks in rallying.

Also, they often throw the car through more angle than the corner is itself by pointing the car away from the turn centre on entry in order to build up enough sideslip velocity to completely saturate the rear axle. So Lowes is 180deg but a rally car might make it into 200-220 by pointing the car out of the turn on entry and exiting in oversteer.

I hope you aren't talking about rallying because I mentioned gravel roads. My commute is 7 km of gravel road into the village, 90 km of tarmac, and 3 or 4 km of gravel road to the PG. The issue was that when ESC was originally introduced we didn't know what sort of limits real drivers could routinely handle on gravel. We'd already had to recalibrate the ABS so that it would handle both tarmac and gravel. Braking distance of a Lexus 400 on gravel was about 150% that of a proper calibration. BTDT at a T junction.

Attention. Please no posts with other car's type (eg: F2, F3, rally, WEC...) or airplane's type (eg: Red Bull Air, F15...)! But yes any past or current F1 cars ONLY!! ;)

I mentioned it because they frequently go over the 30 deg/s threshold you mentioned.

I think good drivers can lower the effective "optical" yaw rate by focussing on a fixed reference point on the track on the corner exit. That way the see a fixed image and the only yawrate information they get is through the inner ear gyroscopes.

Yes, i am sure you can train yourself to cope, I expect drifters would also manage high yaw angles and yaw rates quite happily.
