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.
 
My old diesel boat engine needs about 30 secs to pre heat and then always starts, even after the winter lay up. Modern glow plugs are very different and very efficient, and more expensive.
 
My old Nissan non turbo diesel 4x4 ute needed a few seconds for the GP's to warm up and the light go out before starting but my modern turbo diesel 4x4 ute starts up like a petrol car.
