Let's suppose that a thirty minute drive where I'm impelled to pay attention all the time is safer. It still would take a lot out of me and make me less productive at work.
It's like the traffic circle where people felt less safe. The fact is you need to increase both actual safety and the feeling of safety, otherwise people are less happy and quite rightly aren't going to support the changes.
Not just make you less productive at work, but these roads are inherently roads where you drive more carefully (read slower). Driving slower means longer commutes, and can be correlated to the same economic problem as road congestion (read slower). Richmond estimates that it has saved 18 million dollars from the economic cost of congested roads by providing public transit. There's a lot of money to be lost in the time.
