Telstra stands by the use of hands-free mobiles - what do you think?

Telstra are publicly standing by their ad which advises drivers to use hands-free mobiles, in spite of more research that shows driving using hands-free is worse than driving when drunk. This is part of a report from the Uk Transport Research Lab:

"Using a hands-free mobile phone also proved to be a considerable distraction for drivers. In fact, participants in the study stated that they found it easier to drive drunk than to drive and use a mobile phone (hand-held or hands-free). In addition, drivers using either a hands-free or a hand-held mobile phone significantly missed more road warning signs than when drunk."

What do you all think about Telstra's decision (which can be read via the following link)?
