I don't know if this is in the current plan, but the original

flows

And then open the doors on both sides?

I think they would have to open the doors on the get off side a couple of
seconds before the get on side.

This is what happens in Munich.
There are anouncements on the train to alight from the
correct (by name) side. Regular travellers don't do it
wrong twice though, if you do get off the wrong side you
find yourself stuck on a platform with only down escalators
and no obvious way to get to another level (there are some
stairs but there are no signs to them)

That way people will manage to get off the correct side.

hopefully
