Sort of a catch 22 in this case. Granted nothing happened to you in your case, but to play devil's advocate, hitting a curb, and getting broadsided at the same time, that is an easy recipe for flipping your car. Also would've been easy to nail that utility pole. So I understand that there's lots of things that go on during that split second that you have to decide what to do. But yes, I'm a dad too, so my instinct would be to try to minimize risk to my own family. In my case, I was in your exact situation a few months ago.. I did the same thing you did, except I didn't hit the curb, I went as far over as I could without leaving the roadway. If I was going to hit the curb, I was going to make the other driver hit me into the curb. In my case, nobody got hit, but it didn't stop the other guy from chasing me down, and confronting me at my kid's school in the middle of the hallway. Yelled at me for putting my kids in danger... I interrupted him and reminded him that he ran a stop sign, and then turned into the wrong lane. I told him he should be thanking me for avoiding him, as I could've just T-boned him at 50mph, which is what the speed limit was.
Congrats on the baby tho! I know kids change perspectives. I know I'm a lot mellower with road ragy things, lol... I didn't even get angered by this incident I mentioned. It wasn't until the guy decided to follow me into my kids school, that I got pissed.
