Would be good to have an option to always display the maximum speed limit, as well as have an audible warning if it's exceeded.
I don't need any of the current premium features, but I'd pay for premium to have this. Set an audible alert when +X mph over (current) speed limit (no manually entering/changing the speed limit; have the app just "know" the current speed limit).
Do you mean to make it optional to have the speed limit displayed? Else, we do always display the speed limit, given that we actually have data for the road you're on.
Optional would be good, but I can live with it always displaying. To make it truly useful, though, it needs also to show the current actual speed and provide an audible warning signal when the speed goes over the speed limit.
