ABP, Always Be Passing. This cannot be overstated, it's a lot easier to deal with problems in your field of vision than ones rapidly approaching from behind. That's also why filtering is so important, and it's heinous that it's not allowed in some (most?) states. If you're able to filter you can use your superior acceleration to always be ahead of cars.

It's true of bikes too, that's why treating red lights as stop signs on a bicycle is something that needs wider legal adoption. I often do it anyway and it means that in city traffic I am sometimes able to traverse a block without ever being passed by a car.
