Granted we're in a pretty small district, but when I voted (mid-morning), I saw multiple elderly voters who probably were not able to drive, and were there with companions. Locally they do a good job about calling around and offering rides to people too, although that doesn't address the ID issue.
We did have an issue with parking on the premises though; I had to make about 5 laps through the parking lot, and finally grabbed a space that opened up in a ditch in a grassy side area (not a parking lot). I wondered how those elderly folks had been able to navigate; it was pretty bad and very disorganized. And I mentioned something to the attendants too; if we are to vote, they need to have sufficient parking. It's bad enough that our polling place was moved last year to a location that's way out of the way for everyone who votes there; instead of the old place which was in our neighborhood.
