It's a Arrows, they changed the name of the team just for some seasons.
Like March that was called Leyton House, I still called them March.
So I don't call it Footwork, because all the team staff, members and so are from Arrows, and it was Arrows again, so it's not like BAR that was Tyrrel.
Footwork was the main sponsor of Arrows, so they wanted it to be called Footwork.
Some years after Arrows was suposed to be Tom Walkishaw Racing, or something with the initials TWR. It's why with this change name and change back that they created a rule that a team can only be renamed if they get all other teams aprovall.
I think it's the same with BMW, any team can not let them change their name.
