What he (and I) recognise as rotational steering is demonstrated at 3:10 in the video.
I'd say that what is demonstrated at 3:10 is no technique at all. It's certainly not rotational steering as I've ever seen it taught! It just an abortion of random hand movements with none of the benefits of rotational steering, and none of the control. I would disregard that video and its terminology completely.

Try this instead:

https://www.youtube.com/watch?v=kkQPzRhRnN4&t=...

and notice how he only touches the wheel at (roughly) 9 and 3 o'clock, not wherever the random hand grab happens to land, only crossing over to grab more lock when required, and always grabbing opposite the hand which is still in contact, half a wheel at a time. That's a critical element of rotational steering. By doing that you always know exactly where your hands are on the wheel, where the centre is (and subconsciously which way the front wheels are pointing as a result), and you could return the wheels to dead centre in one movement without looking at your hands.

It's useful for mostly slow-speed tight turns where you need more than a turn of lock, and almost compulsory for track-day hairpins in road cars (which tend to have slow steering racks). And of course catching epic drifts like the driving gods we all are... wink
TBH I don't see either method as clearly being superior. In any case, the important point (in my view) is having a steering style, or selection of styles, that enable us to control the car reliably and comfortably and with adequate precision.

...and when your man comes to fixed grip steering he describes it as fixed input, which to my mind is wrong terminology. It's the grip that is fixed. tongue out

Yes. If you can find a better one in the public domain, please post it.

That's the very same link that I give to my IAM associates when they ask about Pull-Push. Of all the videos I looked at it's probably the best demo of PP, and there's a certain charm about the presentation.

I think that video is perfect as is the young lady - why don't my observers look like that smile

She could work on my cars anytime https://www.youtube.com/watch?v=GEo7KIvhNuk

Indicating when moving back in seems standard practice in North Wales, even if the oncoming traffic is a long way away.

It's been a while, but here's the latest video - advanced drivng in a Tesla Model S 90D:

https://youtu.be/SPhbZ33eU-I

The plan is to upload content on a more regular basis in the coming weeks or months, so lets see how that works out!

Interesting - here's a question, not sure if you know the answer. Given that you don't seem to need to use the brakes much in order to slow, does the Tesla show brake lights at the rear when you lift of completely? Is the deceleration enough that it should?

Yes it does. There was no braking into the right hander at the end of the video, but you'll see the brake lights come on at 17.09.

If you watch the acceleration runs where I've got the camera on the instrument panel, it displays a little picture of the car. amongst other bits of information, this picture shows you when the brake lights are illuminated. A small lift on the accelerator won't light them up, but a sustained lift will make the brake lights come on.

Does it have adjustable levels of regen-coast? I had a ride in a Mitsubishi Outlander PHEV once and it up to "regen level 3" it would not illuminate the brake lights, and it went up to quite a harshly-decelerating 5.

One thing which surprised me about the car, considering how advanced it is, is the lack of adjustability on parameters which, in pretty much all other cars in this price range, would be fitted as standard.

It sits on passive dampers, has no seperate driver modes, throttle response, eco modes, adjustable steering weight or, as you've mentioned, regen modes.

You simply get in it, put it in drive and go.

To be fair, the dampers have been very well executed and the suspension in general does a good job of disguising the car's mass, and the feel and response of the cars controls are also very well engineered, so I never felt the need for any further levels of adjustability.

I was left with slightly mixed feelings about the car though. On the one hand, it's a very nicely presented thing with a comfortable and well-styled interior and extremely strong performance.

On the other hand, it left me a little bit cold at times. The performance is excellent, but it's lacking the engagement of a high-performance internal combustion engined car. Efficiency without drama is just a bit dull isn't it?

I completely get what Tesla are doing and it was interesting what a positive reaction the car got from people who would normally not be in the slightest bit interested in cars. But if I were looking to spend this kind of money on a car, I still think I'd be looking elsewhere.

I'm hoping that Tesla encourages other manufacturers to get on board and make boring cars electric. I have an MPV with a decade-old 1.6 diesel engine so it's slow and not all that great for the environment, and has all the packaging constraints of having a big iron lump at the front. I'd be happy to have 200hp of 2 wheel drive electric power instead, and save a few gallons of fuel per week that could be cracked in the refinery into lovely 99 octane for the fun car.

Edit: It is entertaining that my slot car controller has more braking modes than a class-leading electric car.

I've made another video of our drive up to Northern Scotland. I've included some commentary this time, rather than Ride of the Valkyries and kept it mostly to overtakes, of which this new car makes fairly light work!

I've also included someone else's overtake in there so you can - ahem - compare techniques!

Was up in that area for the weekend, just got back last night.
Overtook at some of the same places as you on Friday afternoon as you did between Contin and Skiag Bridge.

Have you been there when the roads are less busy (and the weather is better!) ?

Hi Reg,

Having failed to identify your car from the video, what is it? It makes a good noise and certainly seems to go well!

Enjoyed the video although it's undoubtedly the case that the camera gives a poorer long range view than you have in reality. There were more than a few times when you committeed to the overtake where I was thingking 'really?' only for the on screen view to open out to confirm what you could obviously already see. Those Scottish roads are just brilliant. I've driven the west coast route up to Fort William numerous times and even after 450 miles to get there, all signs of fatigue disappear as you turn up the side of Loch Lomond and head for the hills!

Just watched the 'Scottish Overtakes' video and learnt A LOT.

The way you handled the silver 5 series BMW who was drifting right over the solid lines was excellent.

A few people have asked the same question, so I've made a little video about my car:
