Its HD Traffic reports use real-time information from other TomTom navigation device owners to plot the fastest for your trip. Because it is truly live, TomTom's system will often suggest a change en route. Many times while testing TomTom's service the traffic rerouting saved me half an hour or more on a road trip. Only TomTom users can benefit from such crowdsourcing, so the next step is to gather a bigger crowd together.
