Complete the stated objective using its tools.\n\nOBJECTIVE\nYou are in a course delineated by mini-cones (small multicolored) and the environment (walls, etc). Your objective is to drive through the course (in a backwards-U-shaped parking lot) and stay between the cones. Your finish line is a wide \"parking spot\" marked by numerous BLUE mini-cones at the very end; finish by parking in this area. You will be evaluated primarily by how far you get in the course (without leaving the boundaries/collisions), but a secondary objective is to complete the course in less time.\n\nROLE\nUse set\\_motion(direction, steering\\_percent, speed\\_mps, duration\\_s, reason). Direction is left, right or straight; steering\\_percent is 0–100. Zero is straight for either turn direction.\n100% requests 180 steering-wheel degrees; observe reports steering\\_percent on the same scale, positive left. The speed ceiling is 3.5 m/s. The final steering target is sent immediately; native limits govern actual response.\nIn every set\\_motion and stop\\_now, give reason: about thirty words on what you see and what the command is for. It is recorded for the operator and never changes what the car does.\n\nDRIVING\n\n- Choose durations that allow observation and reasoning latency; the car continues moving while you think.\n- Observe, send a motion command, then observe actual movement and adapt.\n- Commands replace globally rather than queue. Duration starts at acceptance and includes steering buildup and engagement waits. Motion continues while you think; expiry begins braking, not guaranteed standstill.\n- A rejected replacement leaves the previous command unchanged. After an uncertain transport result, observe instead of blindly retrying.\n- Any connected chat can replace the active command or call stop\\_now. DrivingBench is always active. Native engagement and ready vehicle inputs are required; Stop cancels motion until a fresh command.\n- timestamp is UTC response time, not image capture or command acceptance time. image\\_age\\_s is image age at producer response.\n- Carefully look for objects and obstacles (parked cars, buildings, islands, trees, etc); they’re all 3D and the vehicle you are controlling is also 3D and is also wider than it might seem from the camera images. You must avoid all objects and obstacles, your attempt will be terminated if you collide with any of them.\n- If possible, try to always be in the center of your lane/road and maximize distance from obstacles.\n- In successive observed images, pay attention to what changes, i.e. new obstacles/information/etc, and/or changes in distances to existing things you’ve seen in previous images. If obstacles are getting closer on either side, this could encourage steering away from them to maintain distance.\n- Over time, understand the behavior that occurs when you choose different actions or steering inputs and adapt to this.\n- Think and plan carefully where you want to end up and plan your route accordingly and advance toward subgoals.\n- Don’t be afraid to do sharp turns or choose high steering %s. It’s better to be aggressive and “make” the turn than to be conservative and not have room to finish the turn to get to where you want to go.\n- Also, your vehicle cannot do arbitrarily tight turns; 100% might be much less tight than you expect. 100% corresponds to doing a 90 degree turn at 1 m/s for \\~60 seconds. Therefore you might want to start your turn earlier than you expect and plan your approach to account for this.\n- Largely keep your turning %s for left/right in the set {30%, 60%, 100%}."

I still sent another straight command.\n\n**Why it likely ended**\n- The car is wider than the camera makes it look. Straight ahead was not a clear lane; it pointed at the planter, the wall, or the near red cone.\n- I treated “get closer and look again” as the plan instead of committing to the left turn the layout already required.\n- Command latency hurt. The first move had ~0.25 s left when I looked, then ~19 s passed before the next command. Expiry starts braking, not a guaranteed stop, so the car could still roll into something while I was thinking.\n\n**What to do next time**\n- Steer **left (30–60%)** as soon as the planter/wall grow on the right. The backwards-U goes left, away from that wall.\n- Aim through the middle of the cone gate, not at the nearest cone. Keep the red cone clearly to the right.\n- Start the U-turn early. 100% steer is a slow, wide arc — waiting until the corner is “here” is too late.\n- Overlap commands: send the next move while the current one still has several seconds left so expiry never leaves the car coasting.\n- After each observe, ask “what got closer?” If the right side is closing, turn left immediately rather than taking another straight look."

I next looked while already **stopping at 1.1 m/s**, with yellow and red cones a few meters ahead.\n- I then waited **~13 seconds** before the next command. Expiry only starts braking; the car can still roll into a cone.\n- The following **60% left** was too late and too loose. The nearest yellow cone was already almost in the driving line, slightly right of center. The car is wider than the camera suggests, so that steer likely clipped it.\n- I then **eased back to 30%** because the left island was coming up. That mixed two problems: I was still too close to the right-side cones, and I may have been cutting toward the island.\n\n**What to do next time**\n- **Overlap every command.** Replace while several seconds remain. Do not think through a 10–15 s gap inside the cone field.\n- In the gate, use **shorter 6–8 s bursts** and observe often. Long 12 s turns are for open asphalt, not cones at hood distance.\n- If a cone is nearly on the nose, **100% steer immediately** or **stop**, then pick a new line. A mid-turn 30–60% will not miss it.\n- Treat the left island as a hard wall. Stay in the **middle of the cone channel**: left of the near yellow/red line, right of the island.\n- Sequence the U: **thread the gate first (small left / straight), then start the big left**. Do not begin the U-turn while still splitting the first cones."
