The funeral of Yassar Yaqub has taken place in Huddersfield
He was shot dead by Police on the M62 on Monday night.
Mr Yaqub's coffin was carried into and out of the service through the men's entrance, and mourners embraced as they paid respect to the father-of-two.
He worked as an office clerk and was single, a coroner was told at the opening of his inquest.
The Independent Police Complaints Commission (IPCC) is investigating the death and said none of the officers involved were using body-worn video cameras during the stop of the white Audi in which Mr Yaqub was travelling.
The inquest heard the hard stop'' of the Audi and a Volkswagen Scirocco happened at 6.10pm on Monday. Mr Dalby said four unmarked police cars were involved in the incident with one - a Mercedes - cutting across the front of the Audi.
He said:
"During the incident an officer discharged a firearm in the execution of his duty with the shots going through the windscreen of the Audi."
Mr Dalby said Mr Yaqub was pronounced dead at 6.47pm and was first identified with his fingerprints. A post-mortem examination revealed he died from gunshot wounds to the chest.
A 30-year-old man appeared in court on Friday charged with firearms offences following the police operation. Moshin Amin, of Broomer Street, Dewsbury, appeared before magistrates in Leeds charged with possession of a firearm with intent to cause fear of violence, possession of a sound moderator and possession of ammunition.
Two men, aged 37 and 26, who were also arrested on Monday evening, have been released on police bail pending further inquiries.
