On Traffic Fines

Something to Consider • 139 implied HN points • 26 Feb 23
🇺🇸 U.S. Politics Public Safety
  1. Speeding is harmful because it puts others at risk, so fines are necessary to discourage it. Fines should be proportional to the danger caused, but not excessively punitive to allow for justified speeding in some situations.
  2. Traffic fines should not depend on a driver's income. A speeding rich driver harms others just as much as a poor driver, and fines should reflect that without deterring all speeding, especially in cases where it's efficient.
  3. Instead of relying on fines for profit, speeding should be treated like a toll based on the risk caused. This way, the focus is on protecting others rather than just generating revenue.

Open Source Defense • 56 implied HN points • 18 Feb 25
🇺🇸 U.S. Politics Public Safety

  3. Even though some people do buy a lot of guns quickly, it's a small portion of gun owners. Selling to responsible buyers while preventing illegal purchases is a tough balance for sellers.
