A 77-year-old bus driver had been warned about his deteriorating standard of driving before he crashed into a supermarket and killed two people, a court has heard.
Mr Chander, from Leamington, is unfit to plead or stand trial. He has been excused from attending a "finding-of-facts" trial at Birmingham Crown Court .
The jury heard that despite being told not to drive when he was tired Mr Chander had worked three consecutive 75-hour weeks prior to the crash.
Opening the case against him, prosecution QC Andrew Thomas said Mr Chander had been charged with two counts of causing death by dangerous driving and two of causing serious injury.
Explaining the facts alleged against Mr Chander, Mr Thomas told the court: "This appears to be the case of a driver who put his foot down on the accelerator instead of pressing the brake.
"And instead of realising his mistake, he kept his foot down on the accelerator throughout the journey. The prosecution say that by any objective standard it is shockingly bad driving."
Mr Thomas added Mr Chander did not apply the brakes until "some seconds" after the bus had crashed into the supermarket and come to a halt.
The prosecutor told the jury Mr Chander will not give evidence during the trial and they will be asked to consider whether or not the facts alleged have been proved.
