Having two permanently coupled cars is obvious.

It is NOT obvious that they should have put a toilet in every car. The solution works quite well and you save a potentially large amount of money.

That would affect turning radius, and what tracks the train could run on.

Unless of course you built them like the large buses with a swivel in the middle, but then you get into non-standard stuff.
