An investigation found that Tesla’s Fremont, California, plant had three times as many Occupational Safety and Health Administration safety violations as 10 other US car factories combined.

This isn't "hardcore" or whatever Elon wanted to call it. This is just simply worker abuse and is dangerous. Literally built upon the blood and bones of your workers. We stopped doing this a century ago because no amount of money is worth the loss of limb. Safety standards are an important part of work/life balance.
