Unless the chart is readable on the bus driving towards you and you're deciding if you want to get on, yes. Step 1 for getting on a bus shouldn't be, access the Internet in my opinion. Nor should every other corner need to have signage and what not that blocks walking access and the view of drivers/pedestrians if we are going to share the same traveling spaces. I just want to see the bus, and say I can take that up 15 blocks to save the walk in the rain.
