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

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

Many police officers watch for vehicles without headlights because it's a telltale of a drunk driver.

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.

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

I can't see a problem with imposing fines on drivers who violate traffic safety laws. The speed limit is the speed limit. A red light means stop. These things haven't changed since people got their driver's licenses.

If you think your job requires you to endanger people, get another job.
