Hard disagree. Just because you don’t understand the rationale of a law doesn’t mean it is arbitrary and disconnected from your safety or best interest.

I’ll give a concrete example. In law school I was hired to write a memo on a traffic circle. There was a very deliberate and effective approach to identifying where pedestrian crossings were the safest. And the cross walk itself is an attempt to encourage people to go to the safe areas for crossing.

Cross walks also create a clear zone of liability. If a driver hits a pedestrian in a crosswalk they are deemed at fault. Outside the crosswalk the pedestrian is deemed to have contributed. So the law incentivizes both driver and pedestrian behavior to converge on a known safety pattern in the safer section of the road. So you can jaywalk based on your analysis that it isn’t really that big of a deal or necessary for your safety but at the scale of society the law encourages the safest behavior.

As far as signatures. I would agree there are better systems. But they still serve a valid function.

I had ATT forge mysignature on a contract to try to get me to have to pay an early termination fee. But because I had other documents with my signature I was able to demonstrate that the forgery wasn’t even close to mine. I would honestly rather have that rather than a digital stamp or Docusign.
