You analyzed the video well. You needed to get off the gas when you missed the apex. Your tires were off track by less than the amount of track you missed at the apex.
There are a lot of subtleties going on in that situation though. Around the apex and beyond, I really was at the traction limit of my fading front tires, but maybe not the rear, hard to say. If I had *just* lifted the throttle, the back end might've come around on the left and made things worse. In the moment, I didn't think that the amount I could safely lift the throttle by would be enough to save it. Not that what I did do was much better: I tried to hold the throttle steady and force the car to stay on the road with the steering wheel, which almost never works.

If I had straightened the steering wheel first (to avoid the back end stepping out on throttle lift), and *then* lifted and hit the brakes, I might've shed enough speed (heading in a straight line towards where my wheels went off) that I could've slowed and turned back onto the line at reduced speed. And if I didn't shed enough speed, at least I'd have been more likely to keep going straight off the track instead of what I did.

Either way, at the moment just before the wheels went off the pavement, I should've had the steering wheel dead straight to avoid getting ripped back across the traffic path on the track like I did (due to the pavement wheels suddenly having a lot more grip than the grass wheels). A straight drive off into the grass would've been fine, but cutting back across isn't.
