I can picture it now: you, getting within inches of the car ahead/behind because you've developed good judgment. Meanwhile the car is beeping at you about impending peril!
In the old downtown area of my small city, parallel parking can be aided by the reflection in the shops' plate glass windows. It's easy (and fun) to be able to do millimeter-level parking jobs while some pedestrians stare at you.
