I would rather pay a fine and get the wanted level over and done with than have a potentially perpetual wanted level star for some minor shit I didn't even realize I somehow managed to do and now they just won't leave me the fuck alone. Or, at least be able to surrender, but get to keep all of your shit for not putting up a fight. Hell, bring back police bribe pickups or something, anything.
I don't recall the use of spike strips in IV. At least up to a 3/4 star wanted level. I don't know about 5 or 6 though.
