Product features, Am I wrong

I saw the Vauxhall Corsa Ad today and on it they had the Corsa which when you press a button the back number plate comes out and becomes a bike rack?
Now while i can see this being a very useful function how many people will buy a car because of this, I see the corsa's main customer to be either boy racers or new female drivers, neither of which would possibly need a bike rack?
Was this feature just a waste of time, money and effort?
My fiance doesn't think so so i said if she sees one within the next year with a bike on and gets a pic of it I'll give her £100
How many times do you see a bike on the back of a car?

What do you think?
