[_will_]

"They hope that they won't be sued because" Amazon has enough resources to tie up anyone attempting to sue them in court for 20 years so that any drivers affected by it have long since died or run out of resources themselves to continue the suit.

Sure, they might eventually be sued, but it will take so long to get any results that by the time there's actually a decision on the case (IF there's ever a decision) that the damages will be so minisculely small to a giant like Amazon that it will just be another line item that's lost in the rounding errors of their financial report.

Expected Judgement amount (not very big in the grand scheme of things for Amazon) * % probability of judgement against them = even smaller relative amount relative to things Amazon cares about.
