IANAL but lots of people put unenforceable clauses in contracts just to make laymen think they don't have a shot.

A common one is "this parking lot is not responsible for damage to your car".

To me, small claims is cheap and worth a shot, especially on that first one. Your reasoning is easy to follow.

IANAL but in that hypothetical a 'realistic' case would depend on what evidence and witnesses you have.

Your lawyer would probably question the cop on the stand very hard about why they made you stop there and not let you pull over to the shoulder, assuming the cops don't lie and do admit to commanding you to stop there.

Everyone should have a front-and-rear dashcam with night vision and audio.

IANAL but as I understand it, you license your work to someone who has asked to use it. That's when you negotiate the terms.

Otherwise, you have an automatic exclusive copyright on anything you make, including supermarket lists or doodles on napkins.

Those assholes who aggregate reddit posts are in serial violation of this.
