I have two suggestion about it...
it would be so much greater if all the autovelox were reported every time also if we run under the limit, because if for any reason after the no ringtone pop up I go over I have no notification about the autovelox... it will be su much easier and safer if was introduced the possibility to enable an all time notification

for the section control speed you must integrated a average speed in the section and improve the where the section start and finish
you can copy the Italian app MyWay made by Autostrade per l'Italia SPA

Thanks!
