There is an obvious fix for this, which is to allow drivers the time to find and use a bathroom, even if it is far from their route. There is an obvious reason driver-employing companies don’t do this, which is that it would raise costs and increase delivery times, two things that all customers (both shippers and receivers) absolutely hate. The shipper that implements this unilaterally will instantly become uncompetitive vs shippers that maintain the status quo. Honestly this is a classic case for top-down regulation. Because it forces all companies to solve the problem simultaneously, it should have little effect on the competitive balance. And companies with unhappy customers could blame the government. That also makes it hard to get regulation done. Voters essentially would have to support raising their own prices in order to help truck drivers.
