If it ends up being more sucessful (bringing progress faster than the other strategy), then it actually is less dangerous (even assuming your assessment of how many drivers are ignoring safety measures is correct) - because if it will bring full self-driving faster, it means it will be used faster instead of human drivers, and will cause less casualties than would have been caused by human driving during that period.
