Lewis Hamilton's father Anthony says his son's amazing start to his debut Formula One season has left him dazed.
Father and son celebrate the podium finish in Malaysia
The British driver's second place in Malaysia made him the first man to finish in the top three in his first two races since Peter Arundell in 1964.
"I'm frightened what's going to happen next," said Hamilton Sr. "It's crazy."
Hamilton occupies third place in the drivers' standings, four points behind McLaren team-mate Fernando Alonso and Ferrari's Kimi Raikkonen.
But as he prepares for the third grand prix of the season in Bahrain on Sunday, the 22-year-old from Stevenage refuses to get carried away by his incredible start in Formula One.
"I couldn't be happier, but this is another stepping stone on the steep learning curve that I have ahead of me," he said.
"For sure the next one has to be a win but we have to push together as a team."
Alonso's victory in Malaysia, his first for McLaren, was the team's first since Japan in October 2005.
We cannot be confused about this result
It also provided further vindication of his controversial decision to leave Renault after two hugely successful years with the French manufacturers.
The 25-year-old won six of the first nine races for Renault last year and finished second in the other three as he retained his world title.
However, like Hamilton, the Spaniard is cautioning against over-inflated expectations of his new team despite their impressive start to the season.
"We cannot be confused about this result," Alonso said.
"We have to understand if (Ferrari's Filipe) Massa was leading the race after the first corner, our chance to win the race was extremely difficult because they have the pace on the long runs.
"I think we can all forget that, keep working as we are doing now and everything should be OK."
McLaren head the team standings with 32 points, nine ahead of Ferrari. Renault are down in fourth with just eight following a poor start to the 2007 campaign.
McLaren finished 2006 in third place, after Raikkonen, Juan Pablo Montoya and Pedro de la Rosa failed to register a single win.
