I've figured out why the busses never run on time in Chicago.

It takes about 6 or 7 minutes to load a wheelchair onto a crowded bus. On my way home from lunch, we picked up a lady in a wheelchair, and the driver had to get about 8 people to move, raise the seats, re-configure the fare machine, kneel the bus, lower the stairs, get the wheelchair person locked into place, then raise the stairs, unkneel the bus, re-configure the fare machine again, and wait for everyone to get resituated.

All it takes is two or three of those to throw the whole route off schedule by about a half hour.

I propose some sort of forklift device where the wheel chair gets scooped up and just sort of hangs there until their stop. Much more efficient.
