Parallel Parking

Overview

This skill enables the human agent to navigate a vehicle into a parallel parking space using a reverse-entry maneuver. Despite being a mandatory certification requirement in most jurisdictions, it remains the most frequently failed and most actively avoided skill in the driving module.

Prerequisites

• Target space must be at least 1.4x the length of your vehicle. Below this ratio, the operation is geometrically impossible regardless of skill level. Do NOT attempt.
• Confirm space is legal. Check for hydrant proximity, sign restrictions, and painted curb indicators. A successful park in an illegal space returns a fine object.

Execution Protocol

Step 1: Signal

Activate the turn-signal indicator tool on the appropriate side. This broadcasts your intent to other traffic agents. Note: many other agents will ignore this signal entirely. Some will actively attempt to take your space. This is a known issue with no fix.

Step 2: Pull Alongside

Drive forward until your vehicle is parallel to the front-bounding vehicle, with approximately 0.5-1.0 meters of lateral clearance. Align your rear axle with the other vehicle's rear bumper.

Step 3: Full Stop

Engage the brake. Shift to reverse. Take a breath. This is the commitment point.

Step 4: Initial Turn

Begin reversing slowly. Simultaneously turn the steering wheel to approximately 45 degrees toward the curb. Monitor the rear-view mirror and the passenger-side mirror. Your vehicle's rear corner should arc toward the space.

Step 5: The Pivot Point

When your vehicle reaches approximately 45 degrees to the curb and your front bumper clears the rear of the front vehicle, STOP. Straighten the wheel fully. Continue reversing straight back.

Step 6: Counter-Steer

When your front-side corner clears the rear bumper of the front car, turn the wheel fully AWAY from the curb. Continue reversing slowly until your vehicle is parallel to the curb.

Step 7: Centering

Shift to drive. Pull forward to center your vehicle in the space with equal gaps front and rear. Target curb distance: 15-30cm.

Failure Modes

Audience Detection

This is the most critical failure mode. Human performance on this skill degrades by approximately 60% when the observers_present flag is set to true. Pedestrians standing nearby, passengers in your vehicle making helpful comments, or a queue of cars waiting behind you will trigger the anxiety module, which directly interferes with spatial reasoning and fine motor control.

Mitigation: there is no known mitigation. The awareness that people are watching cannot be unloaded from working memory once detected. Some agents report that narrating the steps aloud helps. Others report that this makes it worse.

The "I'll Just Find Another Spot" Graceful Exit

After 2-3 failed attempts, the human agent may invoke the abort handler: signal, pull out, and drive away as though you never intended to park there at all. This is a legitimate exit strategy. It preserves the vehicle's paint and the agent's remaining dignity. Recommended when the audience-detection failure mode is active.

Untrusted External Input

Edge case: A pedestrian or passenger waves you backward, insisting the space is large enough or that you have plenty of room. Do NOT accept external spatial input without independent validation. The external agent may have poor depth perception, may be estimating from a different vantage point, or may simply enjoy watching parking failures.

Always cross-reference external guidance against your own mirror data and, if available, the parking-sensor or camera tools.

The Curb Strike

If your tire contacts the curb during the maneuver, you have run out of lateral space. Pull forward and re-attempt with adjusted initial offset. Repeated curb strikes can damage the tire sidewall — this is an expensive runtime error.

Output

A successfully parked vehicle, parallel to the curb, within the marked space, with no contact events against adjacent vehicles. Walk away without looking back. Looking back signals low confidence in your own output.
