One of the riders was hit and thrown over a hedge, causing him serious injuries, before the vehicle hit Abdullah, MacDonald said.
He told the court: “The car was coming from the opposite direction and the front offside, or right-hand side of the car, struck Abdullah, who was thrown into the air and sustained catastrophic injuries in the course of that collision, from which there was no hope of recovery.
“The target was not Abdullah, who happened, tragically, to be in the wrong place at the wrong time.
“Instead, it was three lads who were on electric bikes – or two on electric bikes and one on a moped – and who had themselves been travelling on Staniforth Road in the same direction as Abdullah had been walking, but in the opposite direction to the car that struck Abdullah.”
According to the prosecution, the car collided first with one of the riders, La’rome Divers, who had refused to make a statement to police.
MacDonald told the court CCTV footage showed “that this car was deliberately steered onto the wrong side of the road and into the path of the cyclists”, even passing a pedestrian refuge on the wrong side of the road.
He said: “It is the prosecution case that, at no point, was any effort made to slow the vehicle down before the collisions took place.”
MacDonald added the CCTV sound evidence was that the car engine was revved as it approached the riders.
The footage shown in court captured the incident from a number of angles.
The prosecutor said that Zulkernain Ahmed had been driving the car and his brother Armaan had been in the back, along with Mohammed.
Another Ahmed brother, Zain, was the front seat passenger but MacDonald said police had not be able to trace him.
