Someone's Walking (unless that's just beside something else) is a bad name. It doesn't give the idea of a somebody getting kicked out of a car, and is likely to get called chairs
on the title alone. Tropes tend to gravitate toward the name.
I, personally, dislike Type 1 Type 2 style tropes (if you do find it's the best option for your trope, name the types
, seeing "Whatever The Trope Name Is
: type 2 in episode three" on a works page is terrible) but if there's two distinct ways of doing it, it might work. You may want to consider launching a sister trope instead of a type 1/type 2. Hm, there may be a good type 1/type 2 distinction, specifically pertaining to the Put Out Or Get Out
type situations where someone is kicked out of the car, rather than storming out.
You may also want to consider whether or not driving along side is a very important aspect of the trope, particularly in regards to the Clueless example.
