Driving is more or less safe depending on the conditions - if the TSA was requiring workers to drive in on a Friday or Saturday in icy conditions where they otherwise would not that'd be way more dangerous than a 9am commute. Still relatively safe (although I really don't like the characterisation of driving as actually safe - people usually only look at the fatalities and ignore the injury rate which is dramatically higher).
