Tomtom will [URL="http://www.marketingweek.co.uk/tomtom-to-measure-billboard-ad-views/3007828.article"]start[/URL] selling IQroutes speed data to advertisers, for the purpose of showing how many people see a given billboard.\n \nPersonally, I never expected Tomtom to release IQroutes data externally. And this seems like the first step on the slippery slope of giving more detailed personalized tracklog data to advertisers. Tomtom recently gave coupons to people who update their profile demographics, and perhaps this may explain why.\n \nI'm one who feels strongly about privacy, and that's the primary reason why I would never have used Google turn-by-turn. Now I'm not so sure. For now I set my Tomtom profile to dummy demographic data.\n\nEdit: I was thinking of turning off anonymous data sharing because of this, but after I cooled down a bit, I eventually decided to leave that alone. Anonymous data is put to such good use with IQroutes.
