Source? From what I know 6g is the realm of anti-g suit, it seems quite strange to me that it is deemed normal in an attraction used also by children.

Humans are pretty tough, it turns out. And people often are overly conservative in these kinds of discussions. http://rollercoaster.wikia.com/wiki/Highest_G-Force_on_a_Roller_Coaster http://rollercoaster.wikia.com/wiki/Highest_G-Force_on_a_Rol...

  Maybe you don't want to have a transportation system that is as uncomfortable to ride as a rollercoaster. You might want to be able to transport frail elderly people and small children as well.

    This is a test track and a competition. Nobody is claiming to build a passenger hyperloop with these accelerations except for fun.

Google's search result blurb says: > Tower of Terror holds the record for most G-force on any roller coaster in the world, an intense 6.3G. This is nearly twice the amount that the average astronaut experiences when making their way through the atmosphere. So world record for a roller coaster was ~60 m/s2, and that was presumably for a very short duration. On a transit system you don't want roller coaster style restraint systems so g-forces have to be much much lower. Some people might be into "ride a roller coaster from NYC to Boston" but that sounds like a niche market to me.

  To clarify the referenced ride is in Gold Reef City in South Africa and is not the same as the Twilight Zone Tower of Terror at Disneyland

    > Twilight Zone Tower of Terror at Disneyland Which doesn't exist anymore. It's now a Guardians of the Galaxy ride (much better IMO).

      In California. It still exists in Florida.

  Just to add, a competition Jetsprint Boat can pull 7G's in the corners... And that's pretty intense. https://www.knfilters.com/news/news.aspx?id=1444 https://www.knfilters.com/news/news.aspx?id=1444

It highly depends on a direction, see https://en.wikipedia.org/wiki/G-force#/media/File:Human_linear_acceleration_tolerance.svg https://en.wikipedia.org/wiki/G-force#/media/File:Human_line...

6 _sustained_ gs would require a g-suit, but for very brief durations it's not bad. It would be very uncomfortable for passengers though.

That's sustained 6g. Momentary 6g is easy to deal with. But it's not like most people will be experiencing such accelerations in a transportation setting normally.
