Edit to add:
Do you feel is reasonable not to leave a tip for the wait staff if the menu doesn't explicitly state that you should, in large print, and/or you've seen a TV campaign in the last year telling you its a good idea? (Sincere question, no snark intended)
My point being, are there not somethings we expect people to understand by osmosis and observation? The announcement 'Stand Clear, The Doors are Closing' is a fairly unambiguous directive.
I am from a culture where it is customary to tip the wait staff at a restaurant, so I would normally leave a tip. At the same time there are cultures out there when it is not customary to tip, or where tipping is rude (such as Japan, China and South Korea). While I understand it is good etiquette to tip in Canada, I would not pass judgement on someone visiting from one of those countries for not tipping at a restaurant in Canada.
Everyone here closely follows the public transport industry in the GTA, so we are more familiar with operational procedures than the average person. I would not expect the average rider to be as knowledgeable about transit as the people on this forum. When designing passenger-facing safety-critical systems (such as a door’s trap protection), the safety risks present depend on the average passenger’s perception of what is safe and what is not (as opposed to the perceptions or people on a transit forum).
If you were to take a person from another city (where they are are a regular transit rider) and put them on the TTC or GO, they likely would assume that safety in Toronto is comparable to their hometown, and that what is safe in their hometown is safe on TTC/GO. If something is safe in their hometown, but isn’t on TTC/GO, they could potentially get killed or injured when they try it in Toronto.
You can’t educate this safety issue away: if that passenger comes from a place where the trap protection on trains is at the level of an elevator, things that are intuitively unsafe to you may not be to them.
When I visited Vienna last year (where the light-barrier trap protection on their new s-bahn trains covers the whole height of the door, but only the bottom of the door on their high-floor trams), I witnessed a safety incident on a tram where a passenger stuck their hand high up in the doorway of a tram. While she did something unsafe on the tram, I don’t think she was unreasonable, as the action would have been safe on the S-bahn.
