Tesla Safety Score System Faces Challenges in Garage Parking Scenarios

   Following our previous comprehensive guide to Tesla's Safety Score system, recent owner reports reveal specific scenario limitations. Multiple Tesla owners experience score drops during garage parking, raising questions about algorithm practicality.

1. Garage Parking Anomalies

Owners report on Tesla Motors Club consistent issues during garage operations:

  • False hard braking events despite normal driving
  • 1.5% to 2.5% hard braking ratios in garage environments
  • Score drops from 100 to 85-95 points daily
  • Direct impact on Tesla insurance premiums

The problem intensifies during nighttime garage maneuvers, creating double penalties for both timing and braking events.

2. Technical Mechanism Analysis

The safety score calculates hard braking based on deceleration rate, not pedal pressure:

  • Threshold: 0.3g deceleration (approximately 6.7 mph/s)
  • Normal regen braking: 0.2g deceleration
  • System-triggered AEB isn't distinguished from driver actions
Braking Type Deceleration Rate Score Impact
Normal Regen Braking 0.2g No penalty
Hard Braking Threshold 0.3g+ Score penalty
Automatic Emergency Braking Varies Often penalized

3. Official Standards vs Reality

Tesla's hard braking exemptions require two conditions:

  • Hardware 3.0+ with successful yellow light detection
  • Clear camera visibility without obstructions

Garage environments create perfect storm conditions:

  • Low light affects camera performance
  • Limited space requires quicker stops
  • No traffic signals to trigger exemptions
  • System cannot distinguish safety maneuvers from aggressive driving

4. User Responses & System Updates

Owner community has developed two main strategies:

  • Abandon safety score entirely due to oversensitivity
  • Adjust driving habits: use creep mode in garages

Tesla has made improvements in version 2.2:

  • Removed forward collision warnings from scoring
  • Increased hard braking allowance to 5.2%
  • Continued algorithm refinements

The core challenge remains: distinguishing necessary safety actions from truly dangerous driving behavior in private spaces like garages.
