Was the track really wet when this accident happened?

If it was then that tyre being fitted the wrong way round certainly could be the cause. The grooves are designed to channel the water displaced by the footprint backwards & outwards. When the tyre is running in the reverse direction the grooves channel the water from the sides in towards the middle of the tyre. (Note that if that wheel was fitted on the left side of the car the tyre would have been running the correct way)

If it was dry then it would make no significant difference as far as I am aware.

There wont be a chicane there because brazilians love the interlagos layout but be sure to see a ran-off are in that place just to avoid the cars from been tossed back to the middle of the track.
The Brazilian drivers seem to agree on the proposal of more run off, so this will probably be the solution.

So, if it suddenly rains in Abu Dhabi, then someone spins and stops on the racing line without hitting anything, and then gets T-boned by another car, will they modify the circuit too? They can as well ban all the spectators who were standing behind the barrier in that turn, just in case they were sending bad waves.

Okay, a death of a racing driver is not a joking matter, but this knee-jerk reaction is beyond ridiculous. Yes the car bounced back onto the track after hitting a barrier and then was driven into by another car at high speed. The same is likely to happen at the following current Grand Prix circuits:
Melbourne
Monte Carlo
Montreal (Gilles Villeneuve)
Valencia Street Circuit
Spa-Francorchamps
Monza
Singapore Street Circuit
Suzuka
Yeongam (Korean GP)
Interlagos

That's the majority of current F1 tracks. Many are newly built. This list doesn't take into account the danger of a car bouncing back onto the racing line after hitting the pit wall (which can happen anywhere).
Of course there's no problem with all those tracks, until someone dies again, then they'd change the one specific corner in question.

Judging by the simulators I'd say that the current wall going along the most of 3rd sector of Interlagos is safer than many places elsewhere due to the angle it's placed. It's almost impossible to hit it hard (in terms of G forces). In dry conditions everything after Juncao (T12) is flat out in pretty much any car. The real danger out there is the the pitlane entrance. Not only because a spinning car (e.g. due to mechanical failure) can hit the beginning of pit wall, but also because the slowing down line is right on the racing line of a blind corner!

Sure was, in fact it's hard to make anything out of that video because of the rain. And if you ask the people that know more about stock cars most will tell you they don't mix too well with rain.

@Panda, yes that's more or less what happens when people let politics get in the way of rational thinkng.

Ive done what i think could be done to Interlagos to make it safter for the Juncao-Senna do S run as well as a few other iterations as well that i think could be done.

Have i neutered the track too much???

It sounds very strange to me that the car was in good shape yet his head was more or less smashed in. I wonder if the structure did a decent job at absorbing energy, it almost sounds like it was too rigid and shook the driver beyond what the HANS is able to take.
I think that the injuries were due to the way the car got hit. When the t-boning happened the car was already been hit by two or more cars that made it spin and bounce exposing the car in way that the impact came in an odd angle. Plus the structure to the trucks is based on the old stock car.

This is the new brazilian stock car - DTM-based.

Yesterday the brazilian racing federation passed a vote to built the run-off area in curva do cafe. It will stretch for 200m and will have 50m depth. The raun-off will demolish the last set of stands and will be made of a low grip material to avoid the drivers from taking advantage of it.
It is predicted to be ready for the f1 race.

There's no real advantage to be gained. It's flat out anyway and you don't even get near the wall until you're on the main straight.

Oh my... Of all places in T3, I can't imagine how does one get to the wall at any serious speed and angle. Even when there was a river crossing the corner in 2003 GP many cars flew off the track with no serious impacts.
It's a shame, Interlagos will be torn to pieces now.

It appears that the poor chap died from head injuries. In a stock car? Presumably a failure within the car resulted in his head hitting something within the car? Although if the car barrel rolled at speed then his head could have been hitting the roll cage etc. if that was at all damaged in an early time in the accident.

Sad news. :(
