Lawsuits often go in front of juries.
Civil juries do whatever the hell they want.
Every step a company takes to make sure that a reasonable customer will avoid hurting themselves makes it more likely a jury will blame an unreasonable one who hurts themselves being unreasonable.
I’m not talking about the amount.
I’m saying they’re much less predictable, so nonsense like having obvious signs saying “don’t be stupid” can affect their ruling regardless of how necessary it should be.
