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.

I wish the dashboard indicators for lights were standardized throughout the auto industry.

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

It would be helpful to be able to see the layout and for the maps to label what exits to use to get to nearby sites/buildings so you aren't wandering the station trying to read the signs in the crowds.

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

I think that maps showing platform details would be useful to visitors, especially to chaperones of school groups, etc. Also useful would be either a compass rose or an arrow pointing North at every metro exit. Emerging from underground is disorienting, especially at night.

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.
