I do not feel the original poster was being insulting, probably only frustrating that nobody answers the question, but instead puts down his choice of driving. Rather like answering a request for a good vegetarian restaurant by saying you need to eat meat to be healthful, that to me is insulting.
I live near Wien and know the routes well, yes there can be delay or danger on the roads, but I have also seen both on a train as well. Be vigilant and you will have a safe and enjoyable time.
While in vienna you should try the cafe central, and take in an opera, often standing room is available with same day performances.
