Seriously, what makes you think you can consistently turn off at a junction and not make the effort to flick the indicator stork to indicate change of direction? The amount of times I've nearly been run over by drivers not indicating and then blaming me for getting in their way is simply staggering.
The indicators are not there just for road users...
If someone would give me legal power to do so, I would most happily shoot out the tyres on vehicles where drivers forget to do this ever-so-simple act.
