Tesla claims overall they are better, but they may not be telling the truth. One would think regulators have data for the above - but they are not talking about it.
The agency is asking if other similar FSD crashes have occurred in reduced roadway visibility conditions, and if Tesla has updated or modified the FSD system in a way that may affect it in such conditions.
It sure seems like they aren't being very forthcoming with their data between this and being threatened with fines last year for not providing the data. That makes me suspect they still aren't telling the truth.
