The "in-use" photo was in the TTC brochure, wasn't it?
I have mixed feelings on this. It's convenient and helpful for bikers, sure, at the same time it's inconvenient for everyone else. I haven't seen, or used one of the racks however. I can imagine some dolt taking forever to figure it out, to the point where the driver has to come out and help, wasting time. Alright during lighter usage hours, but what about peak hours when everyone is in a hurry to get where they're going.
Thankfully I never need to take the bused routes.
It can be hard to figure things out with 50 sets of eyes on you. TTC should take these racks and bolt them to the exterior walls of some TTC stations around the city so riders can drop by to figure them out under less stressful situations - a trial run as it were.
