Millions of Tesla owners will require hardware upgrades to utilize a future version of the Full Self-Driving software that operates without human supervision. This statement contradicts previous claims that such upgrades would not be necessary.

A Texas Tesla owner reported that his vehicle, using Full Self-Driving (FSD), drove through a lowered railroad crossing arm seconds before a train approached. The owner, Joshua Brown, described this incident as the first time FSD had failed him during his extensive use of the feature.
