I would probably pull him over too but arguably he should be pulled over less than normal, right? The risk that he’s some criminal is probably pretty low since not a lot of criminals would chose a car like that to travel.

On the other hand it probably has an increased likelihood to have technical problems that make it reasonable to pull it over though.

If im a drug smuggler I'm definitely driving the most boring, common car directly BEHIND the banana car.

The cops should know that trick by now - the "distraction car" is literally the plot of "Smokey and the Bandit" from 50 years ago. Nevertheless, you may be right :-)

However, the distraction car is breaking the law in Smokey and the Bandit. It’s not incorrect for them to try and pull it over.

Yes but every good police officer had watched Arrested Development and so knows that there’s always money in the banana stand.

Wow you waited from 2012 to crack this joke with that username

worth it.

What possible technical problem would a cop be qualified to not only recognize and diagnose, but also have any useful input on?

Cops shouldn't be pulling over anybody without either direct evidence of a potential crime or a warrant.
