As it happens, I started to make this back when McLaren weren't doing quite as well as they are now... for exactly the reason you describe. Being able to see pit windows easily for drivers all the way down the field, and observe lap times and relative gaps for drivers makes following the midfield much easier.

Unfortunately I don't handle lapped drivers very well, once they're lapped much of the gap related stuff stops working for them. Thankfully the last year or so the field has been close enough where that's not too much of an issue.
