Giancarlo Fisichella was sorry for the pitstop blunder that cost him the chance of scoring a better result at the Australian Grand Prix.
The Force India driver overshot his pit slot during his first stop, the Roman admitting he was used to his team being in the last pitlane place.
Fisichella's car had to be pushed back in order to have his pitstop, losing several seconds in the process.
He went on to finish in 12th position.
"I'm very disappointed with the mistake I made in the pitstop," said the Italian. "I was just confused with last year as we were always in the last slot in the pitlane, so I just overshot and had to be pulled back into the pits.
"I'm really sad about this as I think we could have got a good result.
"We can take some positives away from this race though - we were able to fight with the others and the car felt good over the race. I'm really looking forward to Malaysia now."
Team-mate Adrian Sutil finished in 10th position after having to pit at the end of the first lap when he hit Mark Webber's Red Bull.
"As expected we got a very exciting race," said Sutil. "I had a good start, but in the first corner I think Webber slowed down and there was nowhere I could go. I damaged my front wing and had to get the car back to the pits. I lost some time behind Heidfeld's BMW: I was faster but there was no way I could get through.
"After the first safety car everything was fine - we had a good strategy with a short stint on the soft tyres in the middle. On the restart I could get past a few cars and then on the hard tyre it went really well. I could finish in 10th position - I think we can be happy with this."
