My husband and I are visitors from Alaska and we are touring in a rented car. We have read with interest the articles and opinions regarding the car crashes involving tourists and locals.
We recognised that we would have to adjust our driving and learn to drive to on the left. Before arrival, I did extensive research on your traffic laws and road signage. At the Queenstown airport, we reviewed the informational road safety videos available free at a kiosk in the rental car section.
However, no amount of reading or reviewing prepares one for sliding into the seat behind the steering wheel and making that first leap into traffic. It was terrifying and intimidating. It is still intimidating and "not natural". Even after driving hundreds of kilometres through Southland and negotiating the multiple narrow and curvy routes, we remain cautious. I still reach for the windshield wiper switch to activate a turn signal, if less often.
I suggest your road system could be improved. Wider shoulders, additional passing lanes, curve-straightening, buckets of yellow paint, better signage, and sturdier guardrails would facilitate road safety for all drivers.
Road shoulders and passing lanes: Many stretches of road have negligible shoulder space, and only two narrow lanes. Increasing the width of paved shoulder space allows and encourages slower moving vehicles to pull over and let a line of cars pass.
