not sure about this statement. are you suggesting once oversteer happens you are supposed to hit the gas to get out of it? i believe backing off the gas is your only option to preventing a full spinout. i think this driver's mistake (once oversteer had already happened) was not turning the steering wheel into the turn quickly enough. just like that vid of the rally car driver operating the sti on that motorcycle street course in europe on r&t who went lock-lock-lock on his steering wheel to escape tragedy

 

I agree with you but you have to define "backing off the gas" more carefully.

If you're in power oversteer like this guy, and you snap the throttle all the way off, you get engine braking (the car is still in gear) which transfers weight off the rear tires and also robs the rear tires of cornering grip in order to support the engine braking grip. For RWD cars in this situation, the engining braking does not affect the front tires and the weight has transferred up front allowing the front tires to dig in contributing more to the oversteer. The term for this situation is Trailing Throttle Oversteer (TTO).

If he had quickly squeezed back on the throttle but left enough throttle on to neutralize engine braking, there would have been no weight transfer, acceleration or braking so all the rear tires' grip would become available for cornering to catch the slide and recover.

It seems pretty clear from the video that he first got in trouble with power oversteer but less clear if he went into TTO after that. It's also hard to tell, but it seems like he did not give enough counter steer either.

Also, he may have been looking at the cars he was trying to avoid instead of the lane ahead where he wanted to go. The car has a tendency to go where you're looking in these situations because you're reacting by instinct and muscle memory, not logic. This may be why he did not get enough counter steer and also why he so neatly placed his car between the other two.

So I see four possible mistakes:

1. Power oversteer
2. TTO
3. Insufficient reverse lock
4. Eyes in the wrong place.

But this is all armchair quarterbacking on my part and speculation based on a not-too-clear video.

I'm not an expert driver, but I am trying to learn this stuff and I am in the middle of reading the Skip Barber book "Going Faster." That means, I am learning what causes these car control issues but I need a lot of track and skid pad practice to make the correct responses instinctual not logical. The time from when the guy in the video was fine until he was over the yellow line in trouble, was what, 1 or 2 seconds. You don't have time to think about all this stuff; it needs to be habit and happen automatically.

I plan to go back next weekend for two more days of SB driving school to get more of this stuff drilled into my head.

I highly recommend the Skip Barber book to anyone who does not already know this stuff and who is interested or wants to track their cars (beyond drag racing) or learn racing.

One last comment: the guy did not spin out (more than 90 degrees) and he did recover but the problem is those other pesky cars in his way. Had he been on a track or skid pad, he probably would not have hit anything - he would just have lost a lot of time in this corner and would know better next time around the track how to get through this corner. This is just one reason why street racing is not such a good plan.

As always: YMMV.

 

Ouch!! Maybe this person needs to learn how to drive powerful cars before driving one!

Wasn't paying much attention the first time through due tot he Lambo. Driver of the video car made two unsafe/illegal turns over the double double yellow.

 

I guess I waited long enough to make a comment.

If you can't make a left turn without hitting anything (I don't care what is the excuse if you're not having a heart attack), let alone sqeezing perfectly b/t 2 opposite cars, you fail as a driver-idioto
