on my tomtom 620 I see occasionally a purple pop-up with a Plus number in front of it

Why would I need to know a route that will take a longer time to travel it. The tomtom already gives the fastest and best route. Why this

Hi @doctormstein1

I had posted an explanation before, comment link- https://discussions.tomtom.com/en/discussion/comment/1648667/#Comment_1648667

The firmware learns your driving behaviour and accordingly gives you an option to take an alternative route which you may have taken before. If that route is faster it shows that green blob and if its slower then it displays the purple blob.

It's just an enhancement feature.
