Susie Wolff has conceded she will know she is 'wasting her time' if Williams do not give her the opportunity to run at the Young Driver Test this year.

The 30-year-old was retained by the Grove-based outfit this season and is focusing all her energies on her role as a development driver. While she said last month that she was hoping to do the Young Driver Test - the date and location of which has still to be confirmed - she has now indicated that it is critical, if she is to progress and move closer to her ultimate goal of trying to secure a race seat.

"For me the next logical step is to do the young drivers test, and do it well, and then see what the next step is after that," the Scot told Reuters. "In theory, I've got enough kilometres in the car to apply for the super-licence [needed to race in F1] but there's absolutely no point in doing that until I'm in a position where I can do something with it.

"They [Williams] haven't said anything [about the Young Driver Test] but for me it has to happen.

"If it doesn't happen, then I'm wasting my time. It's all for nothing. It's got to happen. I am the development driver, so it cannot be that a young driver test comes and you don't put your development driver in. But you never know, so let's see."

Wolff also added that she has no fears about doing the test and is certain she can set competitive times: "There's many people who think it's going to be embarrassing for me to drive on a young driver day, because I'm going to be so far off the pace. For me, it's incredible to hear such comments," she continued.

"I wouldn't be doing aero tests if I hadn't shown some kind of capability. People forget we've been racing at a high level for a long time. It is not like you are just plucked from obscurity and told 'drive the F1 car'."

There have been five female drivers in F1 in the past, the most recent, however, was in 1992 when Giovanna Amati drove for Brabham. Wolff reckons the time is right now for a sixth.

"I think there's quite a big movement just now, people want to see a woman in F1, the momentum is definitely there," she stated. "People are really pushing now and asking why isn't there a woman in F1. For me the timing is good but motorsport is a lot about talent and a little bit about timing and luck.

"[F1 boss] Bernie [Ecclestone] says many things in the press and to the media but behind closed doors he's doing a hell of a lot to help me come into F1 because he knows from a business perspective it has to happen," Susie summed-up.
