I have a minor gripe about PAT policy regarding the T. The official rule is that when you take a bike on, you're supposed to fold up the seats in the wheelchair area and put the bike there. Since there's no way to secure your bike, you're supposed to stand next to it and hold it. The T's acceleration means you'll likely need to hang on to something else too, or risk getting pulled off your feet.
But there's a better place for a bike. Put it opposite the wheelchair area, pushed up against the single seats there, with one handle bar in the space for one seat, and you in the adjacent seat.
Advantages:
1. The cyclist can sit down. It's easy to hook an elbow around the seat tube, and this secures the bike effectively. Lean the bike toward you a bit, and set a pedal against a seat so it keeps your wheels from turning, and you hardly need to even do that.
2. You won't get tired and lose control of the bike, or get dragged while reaching for the bell, so it's safer for other passengers too.
3. This method takes up 2 seats. PAT's way takes 3-5 (depending on whether passengers are brave enough to sit in the row directly behind the wheelchair area, and hope you don't let your bike roll into them).
4. This method obstructs the corridor less. All that's sticking out is one handlebar (plus a few inches for the frame). With PAT's method, there's the bike plus you standing next to it, and passengers have to get around that.
I usually use this method, but occasionally a driver will say to use the wheelchair area. (Today the driver and I compromised, after he told me to use the wheelchair area. I folded down the wheelchair seats on the empty T, then ignored them and used the seats instead, and he didn't make any further fuss.)
It would be great if PAT modified its rules so they didn't require using the wheelchair area, but just required cyclists to get their bikes out of the corridor as much as possible.
