The biased vehicle

An autonomous car powered by AI is currently in the experimental trial stage. The tests take place in a middle-latitude region with a continental climate (warm summers, cold winters, and occasional rain).

The evaluation committee is proposing four different initiatives for comprehensive testing of the vehicle, both in a simulated environment and on actual roads.

One of these initiatives might lead to a biased AI system if it were implemented, such that the vehicle cannot behave properly or make informed decisions under certain conditions.

Identify which one might be the "problematic" initiative?
