Sharp turns, often found at the base of these hills, demand quick adjustments and accurate lane positioning. These conditions test the vehicle’s ability to maintain stability and ensure passenger safety.

Narrow streets and dense traffic

The city’s narrow streets, often lined with parked cars, leave little room for error. You may notice how these tight spaces force vehicles to navigate with extreme caution, especially during peak traffic hours. Dense traffic further complicates the situation, as vehicles must interact with pedestrians, cyclists, and other road users in close proximity.

• Vehicles can become immobilized in bottlenecks, particularly at intersections with heavy traffic.
• Confusion arises when navigating train tracks, which are common in certain areas.
• These challenges highlight the need for advanced systems to handle such complexities effectively.

Dynamic and unpredictable road conditions

San Francisco’s roadways constantly evolve due to construction, temporary closures, and changing traffic patterns. This unpredictability makes it harder for autonomous systems to rely solely on pre-mapped data. Zum Beispiel, intricate intersections require split-second decisions to avoid delays or accidents.
