Qualifying conditions were 'on the limit' - Button

Jenson Button says conditions in qualifying for the United States Grand Prix were "on the limit" as rain continued in Austin.

After qualifying was postponed on Saturday, the session got underway on Sunday morning despite more rain falling, with the FIA insisting all drivers used full wet tyres throughout the session. With conditions deteriorating further during Q2, the final part of qualifying was eventually cancelled.

Asked if it was responsible to run qualifying at all, Button replied: "It’s on the limit.

"Low speed corners you don’t mind aquaplaning but in a high speed corner like Turn 10 that’s proper scary, and where [Carlos] Sainz went off as well. The problem is you don’t know how deep it is, you don’t know what it’s going to feel like when you get there and until you get there. So it’s very tricky.

“The last long right-hander as well, the quick one, again you don’t know suddenly when it’s going to break away. So it’s really difficult. It’s not the correct conditions to drive because you are not in control at all.”

With team-mate Fernando Alonso running a different specification of Honda power unit and out qualifying Button, the 2009 world champion admits it's hard to judge if there is any progress being made in such conditions.

“It’s wet so I’m not really sure, but I didn’t have a very good run anyway. In Q1 it was OK, in Q2 when I went backwards at Turn 10 I think the tread works in a very different way once it has gone backwards and suddenly you have no rear grip. I heard a lot of people struggle with it, I did it on my first timed lap which is a pain but anyway I’m still here now and I’m safe so I’m happy about that.”
