Proper science does. Nugent science doesn't.

Whenever I carried shopping or other goods in a rucksack while cycling, I
found the biggest problem was the inevitable shifting of the load.

Not only because it changed the balance but also because restoring its
position meant I would need to wriggle or writhe in a way which reduced
control.

Of course a cyclist should stop to do this but sometimes it would have to
be every 25 metres making a journey effectively impossible.
