Yes, obviously the danger of getting passed by a much faster silent vehicle is much less in an area with low traffic density, low intersection density, yada yada. I'm glad we finally got to the bottom of your confusion.
Edit: Also I feel like, from your last reply, that you might have taken one or both of my replies in a way that wasn't intended. It's also possible that I didn't word my replies in a good manner. I'm not always good at that. I am genuinely curious about how it is that others can hear loud vehicles behind them when driving while I can't. Your mention of echoes off buildings got me thinking of driving through a big city surrounded by big buildings, and that's an environment I am not familiar with except in pictures and videos. If that's the reason then it answers the question I've had for a couple years now when I first saw someone mention that they hear loud vehicles behind them.
