Not to be a party pooper, F1 cars are built to regulations. The VW isn't, it is also 4wd as opposed to the F1 rwd. The F1 car was also running grooved tyres which were designed to limit the level of grip. Tyre technology and grip has moved on a long way in that time and as the VW was running full slicks it would have had better grip.
Not being a pedant at all. I watched most of Goodwood all weekend and on the Sunday they said that even though the time had been beaten it was an unofficial time. Goodwood have since changed their mind and allowed the unofficial time to stand.
No, but it does mean this "fact" of yours (quoted below) is completely false, made up by you in a desperate attempt to say anything bad about EV's.
(I know "the fact" was just a saying. But I was picked out earlier using a similar expression, so I'll have to point out your "fact" is wrong, despite other contributor chose to give you a pass on this obviously wrong "fact")
Since you watched it, you must have forgotten to mention how ID-R broke the record on its first try on Friday. Then the weather became less ideal and it rained most of Sunday.
Your point being?
Again, you are the one talking complete b******t in an attempt to validate your opinion.

But from the severity of the Regan braking described you are going to have to feather the throttle a lot sooner than in an ICE vehicle because engine braking without the need to change down gears is nowhere near severe.
Unless you drive using the accelerator like a light switch feathering the throttle between fully on and fully off will not induce full regen braking as the fly by wire system knows that its not at 0
)So in that scenario would the EV be doing any regen at all, i.e. putting any energy back into the battery or as the accelerator is feathered/engaged would the EV not be using energy to go down hill where the ICE would be using no fuel.
Or is the regen braking clever enough to realize what is going on and manage to regen some power?
The above is a serious question as I don't know too much detail regarding regen braking. I used to race Electric RC cars where 'lifting off' a little was effectively braking as it lowered the speed of the motor, it was easy to slide the RC cars under 'braking' via the motor speed alone! The drive of the RC cars was connected to the motor on a permanent basis via belt and driveshafts and all wheel drive (could change the diffs to change off power characteristics but that's completely off topic
You are missing the point. Take your foot off the pedal. An ice vehicle engine brakes and the EV starts to Regan braking. If as our friend has assured us, Regan braking in his leaf is like dropping 2-3 gears the EV will slow a lot quicker and in a shorter distance. You will then have to start feathering the throttle to smoothly retain the speed than you would with an ICE engine braking.
The evidence I saw was back in the eighties so can't find a picture or anything to prove it. But basically the back end of the car has to be a specific shape when the airflow had passed over and under the car, the air from over the top rolled down and over on itself pressing on the rear of the car as it does so. It's the reason why some cars will get filthy dirty on the back whilst others remain clean.
The second you hit the brake the engine will still be burning fuel but the injectors will shut off soon after as the engine has no need to fire to keep the engine turning. The only way the engine will remain firing when braking is if the clutch is disengaged or you have put the car in neutral.
If you take your foot off the pedal in a leaf one of two things can happen depending on what mode your in (this bit is the bit that needs proper understanding on here).
Drag coefficient is the drag caused by a body passing through air or a fluid. The better more streamlined the body shape the lower the drag coefficient.
If your throttle is held at a position where there is zero power going in or out of the motor. In some cars, this behaviour is configurable via infotainment or flappy paddle (lift off = no regen). It is akin to coasting in neutral gear. You don't get regenerative braking and motor has very little internal resistance to slow you down. No energy is consumed or captured.So in that scenario would the EV be doing any regen at all, i.e. putting any energy back into the battery or as the accelerator is feathered/engaged would the EV not be using energy to go down hill where the ICE would be using no fuel.

No, YOU are missing the point at the start of this post. But finally gets it near the end, still decides to keep arguing though. Everything is configurable in an EV.
This tail design?
Odd, my '64 reg Leaf in any of the 4 modes (Eco and D/B, making 4 configurable modes) only slows down to the speed mimicking automatic gearbox lifting off brake pedal. I always have to press brake pedal to come to a complete stop.
Not laziness at all for some reason my phone cars started auto correcting regen. I simply hadn't noticed it had done it on those occasions. Writing this post it decided to correct it to regent, but I noticed it as I was watching to see if it would try to replace it with Regan again.
That article seems to assume all airflow is only above the body and along the sides. It totally ignores the airflow under the car.
May well have been. What I remember seeing was a rudimentary drawing of the airflow over the car outline and down the back. At the point of the small vertical area where all the air started to meet again at varying degrees of pressure, the air scrolls over on itself applying a small amount of pressure against the small vertical section.
You clearly have no idea regarding aerodynamics so there is no point continuing - if you want to believe a car can be pushed along by the airflow over the vehicle you have been smoking something strange! It's far better to accept you made a really stupid statement than to keep spouting rubbish!
The "misleading" accusation came from the testing agency that would have preferred all manufacturers use their coarse 5 star rating system. Tesla published more detailed data from their test results.

From what I have read, the model 3 is only safest in it's class, there are other cars in other classes that have proved safer in some respects than the model 3, but Tesla has stated that the car is the safest car that the NHTSA has tested. Basically Tesla have given the car a rating that just doesn't exist.
I did read the article and several others too. Basically Tesla are giving the impression that the NHTSA have said that the model 3 is the safest car when the NHTSA have made no such statement. The NHTSA have every right not to like a manufacturer making such claims on their behalf.

Your source to disprove this graph? This graph (came from Electrek article you linked, but do note the non-zero axis) claims to be "top 50 vehicles tested by NHTSA", completely opposite of what you are saying.
So that's how it is. The industry feels "just above average" safety level is worth a full mark. Making it difficult for the customers to choose safest car available.
Tesla Model 3 being the "safest" car was mentioned in the last couple of weeks. I would classify that as recent.
And you do it again
