Take number of turns into account when routing
When I let TomTom route the trip it picks a route that's far more troublesome.
10 corners and 5 traffic lights.
I always use the Fastest route option, but the one TomTom picks certainly isn't.
I don't know TomTom knows the location of traffic lights* but it certainly knows the corners on the route.
So based on distance and max speed (exactly the same) on both routes the route TomTom selects may seem faster. But in reality sharp corners always show me down. So the average speed on that route is lower.
*=most often there are traffic lights when major roads intersect.
So I think the routing could be improved a bit.
