NO.  I would not.

     complain about them…yes.

      beg them to stop….done that.

          pinch them….. unfortunately yes.

       stop the car and sit while crying silently…….afraid so people.

But I would not put them out of the car, ultimately, I am responsible for their safety, their instruction, their understanding of the rules. Basically, I am saying that if your kids are bickering so bad that you want to put them out of your car ,onto the street…..YOU, as the mom, have to take some of the responsibility.
