Why Spaceflight Will Never Be as Safe as Modern Aviation

That chart is using 15 year old numbers because recent history is less flattering. Strictly speaking the

International Space Station is the safest way to travel, 17,150 mph, and zero deaths. Further, Deaths per billion journeys:

Car: 40 Foot: 40

But wait, more people are ~8x as many people are killed in cars vs walking in the US. So you only walk somewhere every few days?

Let's sanity check that: 1.24 million deaths occurred on the world’s roads. 7 billion people let's say they all average 2 trips a day * 365 days a year. That's ~485 deaths per billion trips.

Ok, so that chart is pure B.S.

I think some countries have orders of magnitude worse road safety, as the USA too had in the past.

On the other hand, most of the world's population doesn't drive a car so the number of trips is probably a lot less, making the number higher.

I think you have good points but your somewhat aggressive style is unnecessary.
