My two favorite "trying to navigate Pittsburgh while disabled" tales:

• Under poor planning: In the South Side, one of the kerb cuts was right next to a sewer grate with wide bars, facing the same way as you'd travel, not against. So you risked wheels getting stuck in the grate.

• In the Selfish Jerks category: I parked in a lot at the South Side Works and was coming up the sidewalk with some friends. As we approached a building with a driveway, someone pulled into the driveway - right in front of us - parked their car on the sidewalk instead of pulling all the way in, jumped out, and ran off.

We spent 5 minutes standing there trying to decide whether to key his car.

Access, at least when I tried to use it 20-odd years ago, required you to be pre-registered with the system [which took 6 months for reasons they couldn't explain], then required 24 hour notice of any non-pre-scheduled trips and I forget how long if you wanted a daily-type of schedule (like, for work).

Then YOU must be early at the pickup point, to make sure there at the right time, but they can show up whenever.

It was a nightmare to try to use.

The only answer is a veggie tray.
