In reply to:
Traffic updates don't do me any good once I'm driving because I've already decided what route to take. In contrast, watching traffic updates on the TV or listening on the alarm clock/radio allows me to leave a bit earlier or plan another route. Same thing goes for weather.
My experience is different. There's not much I can change for the short journey to or from work (normally 20 minutes; the only time it's been over half an hour is once when there was an accident stopping me in a queue for an hour). But traffic info is invaluable for longer journeys to the less-flat bits of Britain.
For example, if I'm going to Scotland, my default route is via the A1 and A66. But I might choose to go along the A14 and up the M1 to Leicester, then across the A50 and up the M6. Or along the M6 all the way, perhaps detouring via Walsall to avoid Junction 8. Or perhaps up the A1, then across the A57 to the M1 and through Bradford (top place for curry).
In other words, there are several decision points along each route, and having some extra information helps make these choices.
My home stereo will switch stations for "News" or "Info" broadcasts; if the empeg could do so, it would occasionally be useful, and definitely have Cool Factor even for those who don't use it
