Seatbelts reduce driver deaths by about 45%. Helmets reduce head injuries by 69%. Airbags save thousands of lives yearly. The evidence is overwhelming: safety equipment works. Yes, some people take more risks, but the protection still outweighs the compensation.

A crumple zone absorbs energy whether you know about it or not. An airbag deploys in milliseconds. A helmet disperses force across a larger area. The physics of protection works regardless of behavior. Even if you drive 5% faster, you're still way safer in a crash.

The original Peltzman Effect study has been criticized. Later research shows compensation exists but is smaller than claimed. People don't fully offset safety benefits - they get maybe 20-30% riskier, not 100%. Net safety still improves significantly with protection.

Risk compensation is real even if partial. Football padding led to harder hits and more concussions. SUV drivers take more risks. Pedestrian and cyclist deaths increased when driver safety improved. We're getting LESS benefit than the equipment could provide. Is that acceptable?

Safety equipment works, but we get less benefit than physics predicts. Seatbelts could reduce deaths by 60% if behavior stayed constant, but we only get ~45% because people drive faster. The compensation is real but partial - we still come out ahead, just not as much as we could.

People maintain a target level of perceived risk. Add protection → Feel safer → Take more risks to get back to "comfortable" danger level. This isn't conscious - it's automatic. We adjust speed, following distance, carefulness without thinking about it.

Drivers with seatbelts and airbags are safer - but pedestrians and cyclists aren't protected by YOUR safety equipment. When drivers feel safer and drive faster or more aggressively, they endanger others who don't share the protection. The user benefits; bystanders may suffer.

Invisible safety works best: crumple zones, side-impact beams - you don't know they're there, so you don't compensate. Environmental design: narrow lanes naturally slow drivers. Swiss cheese model: multiple weak barriers instead of one strong one. Design assuming compensation will happen.

The Peltzman Effect shows safety regulations cause behavior changes that offset benefits. Seatbelt laws reduced driver deaths but increased pedestrian deaths. Football padding improved → head injuries UP because players hit harder. ABS brakes → more tailgating. The net effect is near zero.

Bank bailouts → banks take bigger risks. Antivirus → users click sketchy links. Cloud backups → less careful with data. Insurance → less prevention. Every time we protect people from consequences, they take more risks. The protection enables the risk.

Remove signs, signals, and barriers → accidents DECREASE. Why? People pay attention when they feel unsafe. "Shared space" street design in Europe proves it: perceived danger creates real safety. The safest streets are the ones that FEEL dangerous.

If compensation were complete, traffic deaths wouldn't have declined over 50 years of safety improvements. Seatbelts DO save lives - the data is clear. Helmets DO prevent brain injuries. Maybe compensation is real but partial? And maybe invisible protection like crumple zones works precisely because people can't compensate for what they don't know about?
