So I have two lines of thought here.
One…Can we do the questions of “So where are you coming from anyway” and “So where are you heading” next? Neither one of those are the cop’s business and have absolutely nothing to do with the traffic stop 99.9% of the time. The sole purpose of those questions is to get you to accidentally yourself into admitting to more that they can nail you with.
The other is good luck doing anything about it if the cops decide to ask you anyway. Sure, the cop may not legally be allowed to ask that, but what are you going to do about it if he does? Are you going to be willing to endure the cop dragging the traffic stop out as long as possible, just to annoy you? Are you willing to turn what may have been a warning into a citation because you pissed off the cop? Or worse, are you ready to endure him doing everything he can to nail you with everything but the kitchen sink, and make you go through the courts to fight it?
Making a law that makes it illegal for them to ask these questions does exactly nothing if the citizens are likely to receive further punishment if they refuse to cooperate when the cop asks anyway. The power imbalance is just way, way too lopsided in favor of the cop, and attempting to exercise your rights in these situations may end up causing more harm than good if the cop decides to go on a power trip.
You can beat the rap, but you can’t beat the ride.
Remember: cops get 72 hours to file charges or cut you loose, so they can just arrest and hold you without charges if they want to fuck your life up.
Good luck explaining to your boss that you missed the last 3 days of work because you were in jail, but it’s ok since they didn’t file charges (yet).
