Bad execution: Google maps accessible routes

Google recently launched wheelchair accessible routes on Google maps. The feature is far from good.

1- The data is inaccurate: I used it today in Berlin and it took me to a station with no elevator. I verified by cross referencing with the local app. And there is no obvious feedback mechanism.

2- The routing is weird: sometimes it shows me longer route with later arrival time.

3- The UX sucks: someone using the wheelchair accessible option is less likely to not use it the next time. I have to go to the options menu and choose wheelchair accessible with every search query. Why can’t this be a default option?
