Forum Rider Down and/or notification of minor incidents

You should check before opening a door as it could well kill someone. It's plain careless not to, the passenger deserved to be fined.

IIRC, dooring is classed as assault in some circumstances, so definitely not too harsh.

All this, it's against the law too.

Cyclists die from getting doored, your case went into the right direction, which more to says than this sad case despite all evidence against the driver.
