Marco Andretti emerged unhurt from the dramatic crash at the start of the Sao Paulo IndyCar race, but said Mario Moraes should have been much more careful into the first corner.
Andretti was briefly trapped in his Andretti Autosport car after KV driver Moraes hit the back of him under braking as the field slowed amid dust from the recently repaired track and a three-car accident ahead featuring Moraes' teammate Takuma Sato, Ganassi's Scott Dixon and Penske's Helio Castroneves.
Moraes' car rode up over Andretti's and stayed atop it until they came to rest at the exit of the chicane.
"It's obviously dusty," said Andretti. "I think if you have any common sense, you're not going to stay flat-out if you can't see the car ahead of you. I don't know, I got hit from behind."
The Brazilian said he was caught out by how early the leaders were slowing for the corner.
"The start was very dusty and drivers in front of me were braking early into Turn 1," Moraes said. "By the time I realized it was about 500 meters into the corner, and when I applied the brakes I lost the rear."
