Anyone use it and how do they find it?

For me, at times it's a Godsend, but at others it infuriates me. It seems to be about 50% accurate and will tell me there's traffic where there is none and vice versa.

It even sometimes directs me away from traffic onto an apparently clear route, only to find….. traffic delays.

I appreciate some roads won't have the facility to monitor traffic and TomTom will get all their info from a 3rd party, but I'd hoped for a bit more accuracy.
