I think grid alignment should be improved.
Also, I think that if we display the speeds, they should be converted to km/h, because at least I don't really have an intuitive understanding of m/s.
Also not sure why the bike speed slider does not distinguish itself visually if it's disabled, that can be confusing I guess...

[DIDONAX]

maybe for cycling speed, but for pedestrian i find m/s more intuitive because i can approximate my speed on the fly assuming 1step ~ 1m, and same goes for wheelchair i am sure they have similar intuition. I would say for running/jogging km/h is better but the speed limit doesn't reach that unless i increase it, which i think i should.

I hadn't thought about jogging before, you're right that this could be a use case at least for direct itineraries. So yeah why not increase the limit. I would still favor km/h. E.g. 1.2 m/s sounds really fast to me but 4.32 km/h is actually quite slow (for myself I'm always calculating with 6km/h - 10min/km (which would be yet another unit that one could use :D). But yeah maybe not worth the effort with the stepping etc. so I'm open to leave it with m/s for the time being.
