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

That's the original problem from which the escalator mess stems. There's just too many of them.

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 see any possible excuse for any driver anywhere to endanger people.

Metro shows no signs of being able to make its trains run on time. This occurs during single-tracking and it occurs during normal rush hour service.

Seems like people could behave themselves without making a calculation regarding how likely or unlikely they are to kill other people.

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.
