Funny Advertising Space...?

There are two routes through to the London Underground when you get off an overground train at Waterloo. Either you can head for the main concourse and make your way down the escalators or you can make your way down the stairs off the platform and into the tunnel below.

If you go down the platform stairs you are confronted currently by a huge advertising campaign for the new BMW 6 series, it stretches the width of about six or seven platforms.

Now I can understand the logic of using that space for a large ad campaign. It's a massive blank canvas, millions of people pass by it so it's great exposure and it's never been used before so everyone who walks past will definitely notice the colourful change which has materialised.

But, and in my book it's a pretty big but, I think they've made somewhat of an error in judgement. The stairs down from the platforms are locked outside of commuter times, so the only people who will see that advert are commuters. Sound okay so far? London commuters as a rule commute by London Transport Services, agreed? Sooooo, that means trains, tubes, buses and walking. As far as I can tell, that doesn't include cars... And those that DO use cars won't be walking through the commuter section of Waterloo. So who the hell are they aiming these ads at?!

You could argue it's weekend drivers, but why would weekend drivers want a six series BMW...? They're not exactly "runarounds", they're just really not weekend cars.

Maybe I'm being unfair, but I'm just thinking maybe, just maybe, the amount of money sunk into that particular campaign was not the best they've ever spent...?
