He says it amounts to taxation without representation

My question is: What can you recommend for staying strong in parenting for the good of the child not our own egos or insecurities? I may lose some peaceful good times with my son because I need to say no or have boundaries for him that he kicks against. I want to stay strong and do what is right. I don’t want to give in just so he won go with his dad to simply get what he wants.

That type of hard and fast rule would have its own downsides

Fair enough. But I forgot to mention that picking your route ahead of your trip really helps avoid encounters like these. I try to stick to dedicated bike lanes and side streets as much as I can. Remember, you have been artificially flooding your brain with dopamine for 14 years. Your brain is used to having an unnaturally high level of the chemicals that make you feel good, and it is trying to adjust to now having far lower level of those chemicals. All the feelings you have right now are natural, and you will continue to experience them for some time period..
