Tesla's 'self-driving' software fails at train crossings, some car owners warn
The National Highway Traffic Safety Administration told NBC News that it had spoken to Tesla about mishaps at train crossings.
In 2018, the Association of American Railroads, a trade group, told federal regulators in a letter that it was a complicated problem, requiring self-driving cars to recognize “locomotive headlights, horns, and bells,” because not all rail crossings have gates and flashing lights. According to Musk, the latest versions of FSD don’t even have human-written computer code but instead are end-to-end neural networks, based solely on training data rather than specific rules. Koopman of Carnegie Mellon said Tesla’s choice of training data — the hours of driving video that it feeds into the software to help it learn — is likely to be the root of the rail crossing issue.
