When waze tells me to take the next exit to leave a highway, I would like a button to let it know that I will disobey that direction (I would label it the "NO WAY!" button, or just "REJECT" if you want to be less emphatic).

Currently, if I stay in the highway and the service road runs parallel to it for many miles, waze believes that I am in the service road and that traffic is very fast there. As a result, it keeps sending more drivers that way.
