Is there a way to permanently dismiss an alert? For example, on my way and back to work, I always get a speed camera alert at the same intersection. I now know the alert by heart. Can I permanently dismiss it?
No.

As for a slightly longer answer:
It is difficult to estimate which alerts you no longer want to receive. The only solution I could see would be to add a “don’t warn me again” button to such an alert. But that has already been suggested by the community. Also, this is not a website issue (wrong forum).
