There is an undo button on the lower left corner of the screen. Try it!

If you go to the OSM website, you can sort of get list of all your modification by date in your profile: https://www.openstreetmap.org/user/YOUR_USERNAME
replyAs someone who has enjoyed playing GeoGuessr-like games in the past, I find it a bit fun to enter/guess a completely random username and see what edits it has made. Interestingly, quite a few of them are concentrated in the Germany/Switzerland/Austria region (the US is popular too)
replyEdit: I had no idea that https://www.openstreetmap.org/history shows a list of the most recent changes in a sidebar, and there seems to be a similar trend too in terms of where OpenStreetMap is edited most often.

replyYou can actually split the road into multiple segments and answer each separately if you don't mind the extra effort. I think there should be something like "differs along the way" button which then asks you to pick a point where to cut.
