An alleged terrorist wanted to kill as many people as possible when he drove at cyclists and police outside the Houses of Parliament, a court has heard.
Salih Khater, 30, is said to have steered his car at members of the public before swerving towards police officers and crashing into a security barrier in Westminster on August 14 last year.
The Old Bailey heard that it was a "premeditated and deliberate" attack designed to cause maximum carnage.
Opening his trial, prosecutor Alison Morgan QC said: "On August 14 2018, Salih Khater carried out a premeditated and deliberate attack on civilians and police officers in Parliament Square.
"His weapon was not a gun or a knife but his car.
"First, he drove at cyclists waiting at traffic lights. Then he drove at police officers who were guarding the side entrance to the Palace of Westminster.
"His actions were not a mistake or as a result of some kind of mechanical error to his vehicle.
"They were deliberate and designed to cause maximum death and injury."
She added: "He caused widespread fear and chaos but miraculously, and contrary to his intentions, he did not kill anyone that day.
"Those who were faced with a vehicle being driven at them at high velocity somehow, and largely by their quick responses, managed to avoid death or very serious injury."
Ms Morgan told jurors Khater's reason for the attack was unclear.
But she suggested that by targeting officers guarding the Palace of Westminster the defendant had a "terrorist motive".
She added: "Using his car in the way that he did, driving in the manner and direction he did, the prosecution alleged that it is obvious that he intended to kill as many people as possible."
The Sudanese-born defendant, of Highgate Street, Birmingham, has denied two counts of attempted murder and two alternative charges of attempting to cause grievous bodily harm.
