Pastor Maldonado has accepted the blame after crashing out of the second practice session at the Chinese Grand Prix.
It was not a good Friday for the Venezuelan as he suffered several off-track excursions before his error upon entering the pit lane.
Maldonado slid wide entering the pit lane and crashed into the barriers.
"The incident this afternoon was a mistake from my side; I was a little optimistic on the entry to the pits, and the run off is quite short, but that's how it is," he said.
"It's a tricky part of the track and we've seen incidents there before."
Despite his woes, as well as his five place grid penalty for this weekend's race, Maldonado reckons Lotus can score points.
"The car is improving - the power unit seems to be better and more consistent - so we're making good progress," he said.
"Our qualifying mode is better, which is something we are working on, so hopefully this weekend will be much better for us. Points are realistic, so we'll do our best to achieve that."
