His plan is to say, "I'm not driving, I'm traveling" and then lord over the police officer as they try to apologize for wasting his time.

They think they've figured out the magic spells Trump uses to avoid paying his bills, not realizing that Trump's way of doing it involves lawyers and credible bluffs, including that he has the resources to indefinitely drag out things to make them as expensive as possible for anyone trying to go against him. And it's not clear when it's a bluff and when it isn't because the system is designed for that kind of tactic to be effective, so even Mr. Famously Doesn't Pay His Lawyers can even do it, though he probably had more luck with it before he got so famous for not paying his lawyers.

The problem for them is, it never works out the way they think it will. Especially because the whole premise is treating police like they have no power in a situation where they do, which tends to make them want to be violent.
