There are easily accessible programs to help aging drivers maintain their skills, or recognize when they need to give up their cars.

SafeTrack - I keep saying this - is not going to fix Metro. It's a speeded up track work program, compressing three years of already planned work on the track bed into about a year.

I can't see a problem with imposing fines on drivers who violate traffic safety laws. The speed limit is the speed limit. A red light means stop. These things haven't changed since people got their driver's licenses.

Drivers tend to look for other drivers, rather than for pedestrians or cyclists.

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.

If you're driving more than 50 mph through a neighborhood where the speed limit is 25 mph, I question whether you should keep your driver's license. You're a menace to society.

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.
