I've noticed that on the RTS fleet, the roof hatch has a label instructing a person to "PUSH UP FOR VENTILATION". I've done this a few times when the AC was off/not working, but I have 2 questions about it...
1. Most buses on the fleet (ie the XD40) have a hatch but no instruction to push up for a vent. Does this functionality still exist on those buses, or will I make a fool out of myself for trying?
2. Do B/Os typically have a problem with people doing this?
Thanks!
