This lens is underutilized in the discourse, but people feel it acutely. Even a lot of the anti-cycling stance comes down to, “What am I, poor?” When you are using transportation infrastructure that’s designed with contempt for you, you know, and you don’t want to be there.

There are safety and scheduling reasons for this. They are not merely trying to snub riders. For example, the light rail trains here have a standard for how long they open their doors at each station. It's something like 14 seconds. A vehicle with open doors will also allow passengers to disembark; it's a two-way passage. So should they sit in the station with closed doors, or push off a few yards down to the intersection? Now, other motorists see a train stopped at a station and they think one thing. They see a train stopped and waiting for a red light and they know that it will proceed through on green. It seems weird to imagine a train that lingers at the station as if it's boarding but it's not, it's really waiting for the light to change, and then it will pounce on the opportunity. That's less than predictable behavior, as far as other motorists are concerned.
Our transit authority reminds riders to arrive at the stop 5 minutes early. We're also reminded that if we miss this one, another one is on the way. Passengers need not inherit that toxic road rage.
