I have mastered the Swindon Magic Roundabout.

I can take on anything now.

The world has lost over $50 billion worth of crude oil

Oh no! Did we check under the mattress?

that has not been produced since the Iran war began nearly 50 days ago

Oh, we HAVEN’T lost it. It was just a complete win.

150-200 km. So 2-3x the length of that commute.

3000 calories additional for 72km? I think there is an error woth your calculator, or it may include BMR in the estimate.

Tour de france riders consude about 5000 calories per stage. Though they are obviously optimized for it.

1. The tram is still usable to all ages and abilities, no? So those who call 30 minutes a long journey still have the 5-10 minute journey option.

2. The tram, walking, and rolling makes it less exclusionary than a bridge only accessible by private motor vehicles.

3. The bridge may still be exclusionary, but it is ordera of magnitude less exclusionary than the previous state of affairs (only those with the physical ability to swim that far).

Cycling adds between 250-1000 extra calories per hour, though it varies by speed and weight.

My historicals show I burn ~500/hour on my longtail with my kid on the commute, and an hour of commuting time would be 25 kms travelled. 500 cal is about 500 grams of beans, so 500g of beans per/100 km. For comparison the car I have is 7L/100km.

I can buy 1kg of beans for 5$, and 1L of gas for $1.70. So by bike is $2.50/100km. By car is $11.9/100km. If I fueled solely on sirloin steak (2cal/g) that would be $13/100km.

Now, I happen to fucking love beans and cooking them many ways. But these costs are also ONLY fuel, ignoring all the other costs and benifits associated with both methods of transportation.

For example, I always travel 25kph by bike. In the city the trip average speed by gar is 35kph, so not a big difference. If I’m travelling outside the city, the trip average will be closer of 90 or 100kph by car, and still 25kph by bike.

My bike also costs $0 in insurance and very little in maintenance or repairs. I also get to scrap as much cardio time from my workouts as I put into cycling; either giving me more time in the day, or letting me focus on another activity.

Timothy Zhan’s Thrawn trilogy came out 1991-93.

Then the Timothy Zhan Thrawn trilogy came out in 2017-19.

There’s also the 2020-21 Timothy Zhan Thawn:Acendency trilogy, but I haven’t read that one.

The best part about reading the Thrawn Trilogy, is reading the Thrawn Trilogy afterwards to compare them.

more kinetic energy will impart more speed to the human during the impact impulse.

Partially correct, the speed (technically acceleration) of the human after a collision is limited by the decceleration of the moving object caused by thr human. Since a car and a truck decellerate about the same amount when receiving the counter-acceleration of the human, the force transfer remains similar.

The bowling ball will not slow down in the slightest when is hits the beach ball, accelerating the beach ball up to it’s speed.

The plastic ball will lose significant speed hitting the beach ball, decelerating itself significantly as it accelerates the beach ball.

I’m going to pick some easy math speeds/masses for demonstration. 2,000 kg sedan, 4,000 kg pickup and 100 kg human. Starting velocities of 20m/s and 0m/s. An impact/acceleration time of 1s.

The sedan hits a pedestrian with (f=ma) of 40kN. It takes 2kN to bring the human up to 20 m/s. So the sedan will be somewhere around 38kN, or 19m/s at the end of it and the human absorbing 1.8-2kN.

The truck has f=80kN. Same 2kN for the human. So the truck will be somewhere around 78kN or 19.5m/s at the end. With the human absorbing 1.9-2kN

In either case the we talking a difference of 1.8-2kN for the human. Regardless the mass (and total force) of the vehicle, the relatively small human as a maximum force they can absorb. And that maximum force is heavily related to the speed of the larger object.

Not to say trucks/SUVs aren’t deadly for other reasons (like where and how the force os transferred)

And then there is the SUV class. Aka the non-passenger work vehicle family passenger vehicle.

Like this?

My understanding is that China has always had a cycling culture of some sort, not a 5-10 year explosion like Paris saw?

Most bike-friendly cities I’ve visited in the last ten years fall into two categories: 1) a comprehensive network that’s been intentionally incorporated into the infrastructure across decades, or 2) quick-and-dirty changes that work really well on some streets with a comprehensive network to be desired. Paris has built a comprehensive network with mostly quick-and-dirty changes in less than ten years. And it’s obvious just riding around that these changes continue to iterate. I was most delighted to track how the striping below my feet had been scraped and relocated as evidence that the bike lanes had been expanded. It’s a work in progress, and that progress is working.

I felt that paragraph adressed it pretty clearly. It’s not that Paris is doing better than X Netherland city. It’s that Paris is tackling the problem with a quick and dirty, but still comprehensive, network. An approach that can be modelled in other cities, even without decades of working towards the goal.

An approach that has inspired me to delegate in my own city as a way to get after this.

And property tax isn’t?

Land Value Tax.

Land Value Tax / Georgism.

Transit should be free.

Yes.

There is some nuance to this. Transit SHOULD be free, but it takes extremely strong political will to improve transit (add more funding) once it has been made free.

Example: X transit is 50% government funded and 50% fare funded.

Government decides to make if free, 100% government funded. Great!

Or government decides to increase funding to 100%, but fares remain. Now there is a 150% budget to improve the transit.

At 50 kph tires are louder. From 30-50 kph tires can be louder.

There’s a lot of factors (notably vehicle weight, tires type and tire age)

I know, there’s just a lot of misinformation fighting against wind power right now.

Yup but even then, using crude oil refined to lubictate a wind turbine for 12-18 months worth of power is a better use than burning it for a few seconds of power.

And people are working towards recycling waste lubricating oil back into lubricating oil. https://www.mdpi.com/2076-3298/12/5/135
