Autonomous navigation system

An autonomous navigation system configured to be installed in a vehicle and selectively enable autonomous navigation of the vehicle, wherein the autonomous navigation system comprises:

• at least one processor;
• and
• a memory, storing program instructions that when executed by the at least one processor cause the autonomous navigation system to:
• during manual navigation of a route to a destination:
• evaluate a characterization of an alternative route for at least a portion of the route to determine that a confidence indicator for the characterization of the alternative route exceeds a threshold confidence indication;
• display a proposal to enable autonomous navigation of the vehicle along the alternative route instead of the portion of the route to the destination;
• and
• in response to receiving a request that accepts the proposal, enable autonomous navigation of the vehicle along the alternative route to the destination.

A method comprising:

• performing, by an autonomous navigation system:
• during manual navigation of a route to a destination:
• evaluating a characterization of an alternative route for at least a portion of the route to determine that a confidence indicator for the characterization of the alternative route exceeds a threshold confidence indication;
• displaying a proposal to enable autonomous navigation of the vehicle along the alternative route instead of the portion of the route to the destination;
• and
• in response to receiving a request that accepts the proposal, enabling autonomous navigation of the vehicle along the alternative route to the destination.

One or more non-transitory, computer-readable storage media, storing program instructions that when executed on or across one or more computing devices cause the one or more computing devices to implement an autonomous navigation system that implements:

• during manual navigation of a route to a destination:
• evaluating a characterization of an alternative route for at least a portion of the route to determine that a confidence indicator for the characterization of the alternative route exceeds a threshold confidence indication;
• displaying a proposal to enable autonomous navigation of the vehicle along the alternative route instead of the portion of the route to the destination;
• and
• in response to receiving a request that accepts the proposal, enabling autonomous navigation of the vehicle along the alternative route to the destination.
