Tourist caused accidents in New Zealand

Wednesday, surgery day! Hopefully final surgery for either of us following our April 13 head on with tourists on the wrong side of the road
Unfortunately it means I am unlikely to do any tours 2018 but I was booked out Oct to Feb. 14 to 22 day tours.
The Government is not addressing the issue of overseas drivers and how easy it is to hire a vehicle in NZ.
They say the rental industry is 80% regulated so as a group they have tightened the laws on renting vehicles in NZ. My industry sources say that is hogwash.
I invite anyone reading this to email me or message or just comment. How can we stop accidents like Xiaoli and I had happening?
I want laws to change. Tighter legislation. I am not sure that is the answer so I seek input.
Wednesday is surgery day for me. Praying Xiaoli does not need another operation. Our suffering needs be for a reason.
I look forward to input.
