Why don't cars backfire anymore?

I miss the days of dropping my groceries then diving into the dirt whenever a backfiring car drives by.

    No more carburetors and contact points timing.  The computer took over.

    Fuel delivery through electronic fuel injection EFI killed the backfire. Was a carburetor thing.

    They do when ignition timing is really off.  But then car runs like a snail.

    Fuel Injection replaced the carburetor.

    I have been around for over 80 years. I have never heard one back fire while driving down the street. The only time I ever heard an engine backfire was when someone got the timing wrong during a tuneup or if the ignition wires were mixed up. 

    It is much harder to screw up an electronic timing system but you can still mix up the ignition wires.

      Correct . I'm a "kid" of 72 and have only heard backfire in movies  (and Onslow's heap on "Keeping Up Appearances").  Of course, some in high school had flamethrower/afterburners on their cars - which required a rich fuel mixture and wouldn't work on today's cars - darn.

    Electronic fuel injection rarely pumps excessive fuel into the cylinder, and electronic ignitions rarely fail.
