Driving ETA is highly inaccurate

[PinguDEV-original]

⚠ Have you searched for similar, already existing issues?

Describe the issue
Currently, if you create a route, OrganicMaps is really optimistic with the estimated time of arrival (ETA). While I like the routes built, the needed time is basically always false, which is bad.
I don't mean that traffic isnt calculated, because even without traffic (just traffic lights and stuff), it's not really realistic.

Steps to reproduce
Create a route, drive it, see the difference.

Expected behaviour
A somewhat correct time, well, obviously when there is low traffic.

System information:

• Operating system and its version: CalyxOS with Android 15
• Organic Maps version: 2024.11.27-12-Web
• Device Model: Pixel 6a

Additional context
I suspect that:

1. The speed is thought of being always the maximum (which isnt the case)
2. Traffic lights (or zebra crosswalks) aren't really used
