Lewis Hamilton accepted responsibility for a performance which left him a lowly sixth at the Hungarian Grand Prix.
Hamilton started from pole position but dropped to fourth into Turn 1 before running wide at Turn 6, slipping down to 10th position.
Hamilton survived contact with Felipe Massa early on but then collided with Daniel Ricciardo following the Safety Car period, damaging his front wing.
Hamilton was forced to make an extra stop and was subsequently handed a drive through penalty, from which he recovered to sixth place.
However, he extended his championship advantage to 21 points as Nico Rosberg was eighth after he picked up a puncture following contact with Ricciardo.
"I was all over the place, I don’t have any words to explain it, just a really bad performance for myself, mistakes all over the place, don’t know if it was lack of concentration," he told reporters.
"I pushed, [I] never gave up, but so any obstacles, there's two different directions and each time I chose the wrong one, I can learn a lot from today and take it on the chin."
"Today was incredibly bizarre, do I deserve any points? I didn’t give up and I had good pace but through all that went on through the grace of god I got points but I’ll take a break and come back stronger.
"One of the worst performances I put in for a long long time but we’re all human."
