When I look at the faces of turning drivers, I mostly see them looking in the direction of oncoming motorists rather than at the people they're about to turn into.

Many Saturday mornings, I take 495 from Fairfax to Maryland in the morning, and I'm astonished by the speed of many of the drivers. Even when I drive 70 mph, I'm being passed by people driving 80-90+ at times.

I'm surprised when I see someone doing the logical, commonsense thing: Walk facing the oncoming traffic.

I don't see traffic fines as a substitute for a commuter tax.

I think that maps showing platform details would be useful to visitors, especially to chaperones of school groups, etc. Also useful would be either a compass rose or an arrow pointing North at every metro exit. Emerging from underground is disorienting, especially at night.

I love the cameras and don't mind mailing in my check when I fail to pay attention and go too fast.

I don't believe any sort of traveler does a better job than any other sort of traveler at obeying traffic safety laws. It's difficult to foresee a camera program that can be used with bikers and walkers.
