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

Automate the headlights so drivers can't forget to turn them on in low visibility.

Metro, built in the late 20th century, is the most escalator-dependent system in the world.

I don't know of any source for online maps showing the platform, stairs, escalators, elevators, mezzanines and other station details.

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

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

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.
