Behavior of Tourists in Iceland

I was travelling between Vik and Selfoss today when I noticed a few things. Don't get me wrong, but these criticisms are intended to perhaps also hear from people who think the same.

In Switzerland (where I live) this is normal, but in Iceland I have only noticed very few people who think you can do whatever you want.

Two examples; DC-3 Plane Wreck near Vik -Why does a whole group of travelers have to jump around on one wing of the plane, even though you can see that the parts are collapsing?

Road traffic - why do you have to overtake in 90 km/h zones at 130 km/h in no-overtaking zones and then so closely in bends? There must be a reason for the limitation... Interestingly, all the cars that have done this have been from a car rental company like Europcar.

What do you think about this? Especially with regard to damage to property or harm to nature/landmarks?
