I didn't find that to the case in Australia, as someone who had L's for far longer than is standard.

Mostly it meant that people gave you a wide berth, as learner drivers are unpredictable at times. So basically, what the sign intends.

It surprises me to hear that about NZ? As I think of NZ, as our friendlier cousin.

Just goes to show that our experiences are always hyperlocalised, and it's hard to actually make generalisations without actual data.
