I think the stewards were right in that instance. There is a huge difference between a once-in-a-lifetime event and something that is repeatable throughout a season.

Fernando always seemed pretty nifty in the Ferrari - a bit too often.
Fernando had monster starts in every car not just Ferrari.

Why do teams use black paint instead of something like vantablack paint in high detail areas to hide aspects of design?

Do you think drivers asking for lots of money could be better spent on the car/team, especially with budget caps coming in. Has your team felt the pinch?

Does anyone miss grid girls?

Have you ever successfully cheated pushed the limit of the regs?

Have you ever been up on the podium to take the team trophy?

I actually think he presents very well. He is more open than most other drivers and quite happy to talk about the mental games and welfare of the driver's.

I also believe that he took the champion on and beat him. I could not imagine anyone turning up at Ferrari and beating MS in his day.

how is your 2021 car coming on? understandably you need to be vague here, so comparing against last years car is fine with me. what sort of % increase are we talking and what do you reckon the split is between powertrain developments and aero?

any interesting developments for 2021 from either your team or others you are aware of, has anyone found a big gain the rest of the teams are scratching their heads about?

have your team started on the 2022 car yet and, if so [i'd hope so!] how far along is it?

IIRC the grid sensor is simply an induction loop in the floor that senses movement of the car, it’s a passive system and wouldn’t know when the lights went out.
The loop will have a frequency passing through it in order to couple with the car and detect it moving. This frequency was switched off when the lights go off and could be detected in the car.

I think you are going to drivers paid more because of the budget cap, and then people like their fitness coaches, race engineers, etc will then be employed by the driver.

My impression (can’t prove it) is that the drivers trainer / coach are already paid by the driver, they’re not formally part of the team.

The race engineer is however very much part of the team, and not part of the drivers ‘entourage’. I can’t see them being paid by the driver, now or in the future.

Would the car be able to hear a frequency with the engines and vibrations so loud?

Perhaps a laser (light), How do grid sensors work?

It's an electromagnetic (radio) signal, not an acoustic signal.

Have I just been whooshed?

Interesting. The car in 3rd looks like he went, then lifted off, then went again. The car in 4th went around the same time as the Ferrari ahead of him. The two of them had awesome traction in the first couple of gears though, possibly some sort of (banned at the time?) traction control system rather than a quick-reaction system?

Just by chance I watched this video. It sounds like there is a radio signal to communicate with the lights, the lights are controlled by radio signals.

Possibly, I mean the interface for the race organiser to use the facilities of the track would need to be of a standard.

Good video. That says that the teams worked out the light sequence by listening to radio signals and reverse-engineering the gantry system, and were able to give the driver an audio signal in his earpiece 100ms *before* the lights went out - as opposed to anything that might make the car go automatically, in response to the start signal.

That start where the organisers changed the system was hillarious, where the lights held a little longer than they expected but the front two or three rows all went anyway!

The delay these days is very much variable, from almost nothing to several seconds.

Interesting, do you guys work with of the shelf software like GT suite etc for engine and dynamic simulations etc or is it in house developed? Or maybe both?
Yes I've seen off the shelf stuff used, particularly in the early days of simulation. Over time most teams have moved to in-house or opensource based codes now, I believe.

The reliability of gearboxes seems to have drastically improved, is this down to the variances of the engine not changing dramatically through a season?
The introduction in the regulations that gearboxes had to last a certain number of races drove the improvement in reliability.
