What are the Challenges in Studying ESC from an Epidemiological Perspective?

Despite its benefits, there are challenges in studying ESC epidemiologically:

Confounding Variables: Other factors, such as driver behavior and road conditions, may influence the occurrence of crashes, making it difficult to isolate the effect of ESC.
Data Collection: Reliable data on ESC-equipped vehicles and crash outcomes can be hard to obtain, especially in regions with less developed traffic monitoring systems.
Bias: There could be selection bias if data is only collected from certain types of vehicles or regions.
