I'd like it if cars had a warning system for when you open the street-side door, as well.
I know far too many people who have gotten broken bones by having someone open their door unexpectedly into the bike lane.

I try to pull as close as I can to block bikes from getting between me and the curb and still have idiots trying to do 20mph in an impossibly tiny gap.
Disclaimer: I avoid the issue by travelling in the center of the auto traffic lane. If you don't like that, tough luck.
I hope that was sarcasm on your part...
I agree that this is better left to a warning indicator.
