    I've noticed that many new diesel drivers just get in and turn on the ignition immediately instead of waiting for the glow plug light to go off.

    Does this matter much? Why did people used to always wait for the glow plug light to go out and now don't bother? Are modern diesels more tolerant?

    Mine usually starts straight away unless it's been really really cold and I need to wait for the glow plugs to warm up.

    No glow plug warm up time needed in a modern diesel.I just start up like it was a petrol motor.
    It has started up on the first turn of the key in -5 degrees and covered with ice after being left outside overnight.

    What he said, but if it too cold outside doing it won't cause any harm.
