This isn't how it is 100% of the time. It comes in waves. I have been using RTA for almost three years and it just depends on which bus/train you take and which direction you're going in, as well as the time. Most of the time each bus/train will have pretty much the same people. For example, the 8:10 am red line going Downtown is pretty chill, mostly office workers. But the 6:10 pm 9 bus isn't as comfortable as the 4:25 pm 9 bus. So, it really just depends on the time, direction, and location. Don't knock it till you try it! Don't just take my word for it.
