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

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.

My philosophy is: Everybody needs to look out for everybody else.

Motors that are vulnerable to shorting out because of snow ingestion should have snow filters installed over air intakes, and spare motors should be ready to replace any failed motors.

When different generations of cars are combined into one train, it messes with the loudspeaker system.

I don't see any possible excuse for any driver anywhere to endanger people.

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