Wa Kgosi said he thought that by taking the lane of the far right, the Corolla was on its way to the car rental parking or taking a shortcut to domestic arrivals.
“I was so surprised because he was travelling at a high speed, but I thought maybe he is rushing for a flight because it was early in the morning,” he said.
“In a split second after taking the far right [lane], he went straight into the pillar. The Corolla spun around and the bumper came off. When I drove past, I saw it was badly damaged,” Wa Kgosi he added.
The 47-year-old said he initially thought the it was an Uber or shuttle driver because of the make of vehicle.
“I didn’t stop because I was with a client. When I came back from the airport I saw some police there and tape around the car,” he said.
Wa Kgosi said he saw a picture of the crash trending on Twitter later on Monday, and then realised that it was the same accident he had witnessed.
“This Corolla, I saw it in the morning. That’s how I found out it was Gavin Watson,” he said.
“There wasn’t any distraction in his way. Maybe he was texting and driving, but I don’t know.”
