People tend not to react to parking violations by taking the law in their own hands with capricious, violent aggression because in general, Americans tend to be civil and respect the rule of law. Less so in NYC, but still broadly true.

Cyclists can't be too aggressive to drivers. Many drivers already seem to have a deep hatred for cyclists as a group, and frankly it's all to easy for a driver to injure or even kill a cyclist through negligence. Open hostility towards drivers in the short term would quickly become catastrophic in the long term.

If cyclists pick a war with the general public, I think they'll lose. They're already unpopular (this website notwithstanding.)

I would support this. Pedestrians should be able to wack cyclists on the sidewalk, and stab e-bikers, however. Certainly violence is the answer to enforcement issues, and not police.

I wish we would, but I’m just not that confrontational, and am worried about getting in trouble for that. Plus half the cars in question are for cops.

Would rather the law be on my side
