How do you do the "saving"? Is their situation better off after your encounter better than it was before?
If the Israelis stopped planting the Lebanese would that be "saving" them (as TV news often says in such circumstances) or merely a cessation of the killing?
When driving I don't need to treat cyclists any differently to any other road user. They all get in the way.
On a driving errand last evening, I did not see a single cyclist but I had 3 drivers performing a sudden lane change in front of me. Two were mistakes, one deliberate. The latter was a person in a 4x4 (no, I am not surprised). None of these were a problem because I have been round long enough to anticipate them. Whether a person on a bike does it or a person in a 4x4 does it makes absolutely no difference to my defensive manouevre. The only difference would have been the victim had I done nothing about it.
A lot of drivers think they are heroes in a situation. Utter rot.
Ignoring rules (which you are probably complaining about) doesn't make someone unsend. Send people often ignore rules more than the unsend.
