I wasn't talking about a responsibility to government either.

The Non-Aggression principle means that we don't have a right to physically harm or endanger non-consenting others or their property and they don't have the right to do that to us. If we do harm or endanger non-consenting others or their property, they are within their right to use force against us or to hire agents to do it for them.

If we approach an intersection with the light out, we don't have a responsibility to "society" to proceed with caution, but we do have a responsibility not to harm or endanger those particular individuals in the intersection. If refusing to proceed with caution would endanger them, we'd be compelled to proceed with caution or face the consequences.

If there were nobody at the intersection for miles, we'd have no responsibility to slow down. If we chose to speed through an intersection because we didn't see someone, but we hit someone anyway, we'd be criminally responsible for our negligence, damage, harm, and endangerment we've caused.
