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

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.

Back in 2011, when the weekend maintenance disruptions got more aggressive, we were told that the work on weekends and at night and midday would be enough to get the system back to a state of good repair.

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

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.

The cars themselves are getting smarter and will be increasingly able to assist drivers - to the point where the cars will be completely automated.

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