The 17-year-old's friends had stopped by his house this past Monday on their way to the beach, but his dad quickly put the kibosh on his plans.
The two boys and three girls took off without him, but didn't get far.
While heading south on Jamboree Road in Newport Beach, driver Abdulrahman Alyahyan, 17, lost control of his Infiniti sedan and crashed into a tree, splitting the car in half and killing himself and three others.
The fifth victim died in hospital.
"I was supposed to be with them in the car, that's why there were three girls," Tamer said.
The teens had planned a triple date.
Police say speed was a factor in the deadliest Newport Beach car accident in years, but the exact cause of the crash remains under investigation.
