How right you are. But, speed limits are generally set to what is deemed safe when fit driver is operating a safe and properly maintained vehicle on a clear, dry roadway under clear, blue skies. Maximum speed under optimum conditions. Less than optimum, drivers are supposed to adjust accordingly.
I wasn't there and don't know the specifics of the circumstances. But, assuming the road was in good shape, dry. Weather was good, sunny and clear with good visibility. And, driver was fit with no problems or distractions (illness, injury, mental conditions such as frustration, anxiety, anger). All in order then 20mph is probably OK. But, if anything is less than ideal, revise speed down.
