Jenson Button says aquaplaning is making conditions too difficult for drivers after qualifying for the United States Grand Prix was curtailed by continuing bad weather.
Having already been postponed until Sunday morning following Saturday's storms, though the qualifying session got away on time, drivers were still faced with the challenge of rain and a sodden track.
With conditions seemingly worsening as the session progressed and several drivers – including Button - spinning at turn ten in particular, qualifying was eventually cancelled ahead of Q3 and grid positions determined by Q2 results.
Going on to qualify 13th – which will become 11th once penalties ahead are taken into account -, Button says he was 'not in control at all'.
“It's on the limit,” he said. “The problem is you don't know where the aquaplaning is, there is water all over the circuit but some areas are deeper than others Low speed corners you don't mind aquaplaning but in a high speed corner like Turn 10 that's proper scary, and where Sainz went off as well (turn four).
“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. It's not the correct conditions to drive because you are not in control at all.”
