Oxygen might not be flammable, but it is caustic. Plus, does the distinction of what is flammable really matter when spilled LOX is 'allowing' everything around it to combust at the slightest spark?

It's strange that oxygen cannot be transported at night. In Europe all the critical and big volume transports goes often at night (wind turbines parts, ship components etc.)

It would depend on infrastructure quality and traffic law adherence.

Lots of places around the world have really terrible roads and nonexistent or nearly entirely unenforced road laws. Places like that you might want to be careful to not drive an enormous tank of flaming death around when you’re not so sure you can see each of 500 pot holes, or an oncoming driver.

Basic infrastructure things are easily taken for granted.

You never have been to India or have never seen a video of a street in India. There are no streets as we in the western know. There is a road and traffic just everywhere and nobody cares about traffic rules. It‘s a dangerous place to live. [Maybe a bit exxagarated].

Otherwise you would know that this _may easily_ result in an accident and no-one wants to have a truck full of O2 to blow up in the night in the middle of nowhere. At least during the day „you see where you go“.

You don’t lose an entire city block if a wind turbine truck flips and spills it’s cargo in a bad crash.
