Car chase: Bullitt or French Connection, F&F is CGI BS.
Gun fight: Open Range or Heat
Fight: Heston versus Peck in The Big Country (totally realistic, not fake like all today crap). Enter the Dragon.
A highly underrated movie for firefight is Tears of the Sun.
Yes, a very realistic shootout in the streets of Los Angeles. Well choreographed and well shot and well directed. Also, IIRC, the first time Deniro and Pacino were in the same movie. Not sure of the director, but it looked like a Scorsese film.
Sorry guy, but you're wrong. Most is stunt drivers on closed courses in the countries the story is about, or a similar looking country.
I've read much about the stunts in that franchise. Although Bullit originally set the standard, F&F has taken it to a level that the Bullit director couldn't imagine or afford. Yes, some is CGI. I'm somewhat of a film critic (concept, story, plot, acting, direction, cinematography, action sequences) so I can tell the difference between live action and CGI. Maybe not always, but the F&F franchise actually has real car sequences.
