No.



I've heard they even take out all the seats except the drivers to get

the best result.



You've heard wrong.



They certainly don't test using real driving conditions such as on road

that aren't 100% straight woithout hills or dumps or stops at lights

That's not the manufacturers way of doing it.
It was on TV last year how they get the mpg for some cars, which included removing the seats and even the brake pads.
