Not those roads, highways. Highways are designed to enter, stay on the highway without stopping except to wait in a traffic jam, then leave. This is terrible for buses which need to stop in-between.
Ideally they would take the opportunity while building the highway to build a parallel busway, but that tends not to happen
1950 as far as I can tell. Every year since then, traffic has killed more people than wars.
It's worse here than in Aus.
We can't answer any of these questions without knowing where you live. Some places in the world have trains that go near national parks(or similar).
Generally a train that's rural enough to stop near national parks will have space for bikes.
Honestly, for most places in the states I believe you're pretty out of luck. The majority sentiment of this community is don't feel bad for using a car if it's the best tool for the job.
By the way, 1 tablespoon of peanut butter does not weigh 14.79 grams. 1 US tablespoon is a unit of volume that's equal to 14.79 milliliters(mils). Grams are a unit of mass. In order to convert between them we need the density. Because the metric system is great, the density of water is 1g/mil, so 1 US tablespoon of water weighs exactly 14.79 mils. However the density of peanut butter is a bit higher, so the US tablespoon of peanut butter will weigh a bit more.
Additional pedantry, yes I did have to write US tablespoon every time. A US tablespoon is 14.79mils, a metric tablespoon is 15mils, a traditional Australian tablespoon was 20mils although now they mostly use metric tablespoons.
I liked Quora as recently as a few years ago, it had some nice explanations that you couldn't get anywhere else. Obviously you have to take everything with a grain of salt, but you have to do that anywhere on the internet.
The thing is, once they started talking about underground, the whole project got so silly that it was obviously never going to happen. $30 billion for underground light rail wiggling all over the place saving very little time on the trip to the airport, it's clearly nonsense from people that are trying to get the project scrapped. So this money was genuinely and intentionally wasted by the public service and the consultants. Although the new government isn't helping since they wanted the project scrapped too.
Spending weeks cycling through a tunnel would be a mind bending experience. I would totally do it.
I was up all night chasing them away from my tent, they're insane.
I've done it, it's a pretty ordinary track and not dangerous if you have some common sense. The top part by the pylon(near to OP's picture) might be the best view I've ever seen! Take the steep part slowly and carefully especially if it's wet, don't go on a steep snow slope if you don't have crampons and ice axe, take enough warm clothes and waterproofs for the alpine environment, take a map. It's just because it's so accessible, and people think that it's going to be the same as the well built tourist roads like the West Matukituki and Rees-Dart.
And watch out for the kea, they will stop at nothing to steal and destroy all your stuff.
Because they hit an elephant calf. Driving too fast to avoid hitting an obstacle is negligent.
This chart ignores one very important detail. Exercise is good for you. Those bars should be negative since it's good energy expenditure.
