Atlas's ETA is too optimistic
**_- app version: Cardinal Maps 0.16.1-arm64_**
## The problem
**Describe precisely the problem you're facing and add screenshots to illustrate**
When I was arriving near my destination I realized the ETA had changed and Atlas was estimating I would walk 400 meters in less than a minute (it changed to 300m when I was taking the screenshot)
{height=600}
Additional irrealistic ETAs
{width=292 height=600} {width=292 height=600} {width=292 height=600} {width=292 height=600}
