Anti-Lock Braking Systems
- 1970s research shows antilock brakes (ABS) really work
- Maintain steering control on slippery surfaces
- Reduce skidding
- Reduce accident rates
- Antilock brakes available in US since 1978
- Accident rates did not go down
- Everybody was puzzled
- Explanation so far
- Drivers "compensate" for ABS
- Feel "safer" and take extra risks
- Push the envelope
- Result: get into situations where ABS can't save them
- Unintended result: Drivers take more risks
