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.

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