Tesla Self-Driving FSD 12.3.6 Review
1. Check the status of intervention
Intervention Case 1 (one occurrence). The dilemma of concession shown at a narrow range. An unprotected left turn occurs at the same time as a vehicle facing each other at a one-lane intersection. Unlike the one-lane intersection of two or more round trips, the one-lane intersection cannot make a left turn at the same time. The FSD that commanded the vehicle in front of the vehicle and the driver in the preceding vehicle all actively began to make concessions. The problem is timing. The situation in which two vehicles make concessions at the same time, move forward a little at the same time, and make concessions at the same time and move at the same time is repeated three times. The distance between the two vehicles from the center of the intersection is too close to each other to intervene. After braking and stopping completely, yield so that the vehicle in front can move first.
In the case of general driving environments, the ability to respond to complex traffic environments and ambiguous driving conditions is clearly full. In a congested environment with a lot of cars, there are frequent situations in which you have to intervene or intervene. Whether aggressive or vice versa, as long as the driver of the other vehicle is clear about the driving attitude, the response to this was perfect and very impressive. There were cases in which the vehicle entered from the alley on the right side of the road while driving straight or when it turned around, and the person who looked at it as a supervisor sometimes flinched, but moved without any problems because Right-of-Way is a clearly defined traffic environment. It was judged that it was very unusual for the dilemma of concession as in the above case to occur. However, it is also necessary to secure the ability to respond to such situations.
Intervention Case 2 (one occurrence). Deceleration of unknown reason occurs in the process of turning left to enter the shopping mall parking lot. Intervention to maintain traffic flow. Also, another deceleration of unknown reason occurs while making a left turn after waiting for a signal at an intersection. However, in this situation, the deceleration intensity is low and acceleration resumes immediately and does not intervene.
Intervention Case 3 (one occurrence). On a highway with a speed limit of 110 km/h, the driving speed suddenly decreases to 85 km/h. Automatic Set Speed Offset was activated, and it is left as it is. There is no change after about 30 seconds, so intervention is made not to interfere with traffic flow.
Intervention Case 4 (one occurrence). Facing an unusual road construction site while driving on a highway. No people or equipment have been put into the site yet, but traffic cones have blocked the right end lane and left it empty for about 3-4 kilometers. The problem is that the gap between traffic cones was too far. In a slightly curved road environment, the next cone was barely visible. Intervention was seen as an attempt to enter the right end lane between the lean cone and the cone.
Intervention Case 5 (2 occurrences). 1) Head-to-head situation occurs in a restaurant parking lot with another vehicle. The road is so narrow that both vehicles cannot pass at the same time, so either side of the road is required to reverse. 2) Turn left to enter a narrow road to find a parking space in the supermarket parking lot, and a head-to-head situation occurs in which the vehicle parked on the road exits. It was necessary to decide to reverse or give up entering the road and drive straight. In both cases, it could not be left for a long time, so intervention occurred.
Intervention Case 6 (1 occurrence). Driving close to curb during right turn. Intervention with wheel scratching.
Intervention Case 7 (one occurrence). Intervention by a U-turn failure at the end of a dead end. There was plenty of round space for a U-turn, but the software gave up driving. The only case in the entire driving experience where complete abandonment of driving was shown. It is judged that the lack of a signal system for a U-turn unlike ordinary roads was the cause. As the U-turn is the first driving capability introduced in the V12, it seems that more training is needed.
Intervention Case 8 (0 occurrence). When entering the highway, there are many cases where you wish you had entered the confluence lane a little earlier. Only at the end of the confluence lane disappear did you enter a new highway lane. Wanted to intervene but persevered.
Intervention Case 9 (0 occurrence). Navigation requires a left turn at the forward intersection. However, left turn failed. Turn right after U-turn. On the same road, the mistake was repeated twice. We judged that we lacked complete understanding of the specific road environment. This road is not a general intersection, but a separate space where left-turn lanes and straight lanes have bumps from about 100 meters before reaching the intersection. For a general intersection, you could have entered the left-turn lane slowly, but you had to move the road to the left-turn lane early on. It did not intervene, but it was regrettable that it failed repeatedly in the driving environment that could be judged by the human eye and brain.
2. Check for improvements compared to previous versions
- Improved convenience: drastically reduced nagging (handle shaking). It was 12.3.6 instead of 12.4.3, so it’s not 100% but 99% if you keep your hand on the handle.
- More efficient flow design: Additional U-turn capabilities have helped create new routes immediately and reflect them in driving if they are difficult or complex to perform existing routes.
- Higher Cognition Accuracy: 1) Improving road environmental awareness (avoiding fine roads while driving at high speeds), 2) Improving dynamic object recognition (unlike V11, ignoring and moving forward with no evasive maneuvers when a plastic bag flew in).
- Faster path judgment: Reduce hesitancy on two-pronged roads with the same score (V11 often confirms hesitancy in choosing a road with the same score). For example, when entering a left-turn lane, if there are two left-turnable lanes, you often hesitate to go between the two. The slight difference in score between the two lanes (front) is possible because the same goal can be performed (left turn) whichever path is taken
