It’s easy to complain about something small making things less safe but no-one is going to say “the circuit itself unsafe”. I think that’s why.

here’s a mad idea…
As everyone (pretty much) how goes off where Sergio did goes at the same angle, why not have an armco barrier that starts where the curb for the chicane meets the current armco (at the chicane entry) and ends at the point of danger. The run off would be gone but instead of an impact there would be a deflection and no sudden loss of momentum.
But the bad thing is that they will slide onto the track and would mean a safetycar during a race situation.

Rosberg (who ought to know as a local) said there’s room to move the whole thing back at least 50m. That should lessen the impact to some degree, though if they’re already a sled at that point I’m not sure how much velocity they would lose in 50m.

I Don’t understand why they don’t put a Tyre Barrier in the middle of that runoff their. Its a simple fix, no one cuts and gets away with it, and it’ll lessen any impact with the tecpro barrier further in by a lot. This would be a standing barrier, not with a wall behind it. See the Sao Paulo Street Circuit that Indy uses. Turn 1 has a large runoff with standing barriers. It’d work wouldn’t it?

Watching the race today, it seemed to be like there is space to move the chicane towards the tunnel a bit. That way the barrier would be much further from the apex of the corner. The main problem I can see with that is that it’d make for a longer straight between the chicane and Tabac, so perhaps it’d make one corner more dangerous while making safer.

I don’t know how good my description was, so here’s a little diagram of what I mean: http://imageshack.us/photo/my-images/233/nouvelle.jpg/

I think the problem would remain anyway ned, once the wheels are off the ground the cars dont slow down very well, and that bump would still be in the middle of the braking zone.

The only way I can see to make it safer is to try to level it out a bit, but then you’d lose some of the spectacle so I would rather they didn’t. Frankly I think it’s pretty safe as it is, while you couldn’t really call Perez’s accident freak, it was unusual the way he ended up, and was down to his error in the end.

Back on topic, I still think tecpro is the way to go, too many things can go wrong with a tyre wall.

I think they should maybe keep the gradient, but move it further back so it’s not in the braking zone and if anything happens it’s far away from the barrier. Then everyone can be happy!

After seeing both those accidents this weekend, I think it might be a good idea to have a long barrier that joins the barriers on the right hand side of the track from before the chicane to the barriers after the chicane at a very oblique angle.

That way, if a car loses control there, when they hit the barriers, they hit at an oblique angle so that there isn’t a rapid deceleration, and the tecpro barriers can gradually absorb the impact along their entire length, as opposed to an isolated application of force on a particular spot.

Your idea will be good if it does not close the escape way out (I do not think that the FIA accepts that).
And you are right when you explain the gradual absorption of the entire line of barriers because unlike the tires, they are not fixed or connected by metal rods, but by a tension system of straps which can be less rigid (40% absorption of energy by more than the tires, data from the DEKRA crash tests) and especially do not send back the car on the center of the track (boomerang effect).

Yes, I think Webber made a reference to being “spat back out” by the tyre barrier, however as he himself found in Korea, although it means you’re not a sitting duck in a wall for the next driver to come off, you’re actually a sitting duck in the race track!
