Repressed memory from when I was 1 or 2?

This may be triggering.

When I was between 1 and 2 years old, my father, who I'm almost positive is a sociopath, was abusive to my mother. He raped her at least once that she's told me, and that was how my sister was conceived. When my mother was pregnant with her, we were all in the car driving somewhere, and while driving down the highway at at over 100 km's a hour he reached over, took off her seatbelt and tried to kill her and my unborn sister by pushing her out of the car. I was in the backseat, and witnessed it all. Luckily my mom held on for dear life and Dad wasn't able to push her out, but my mother said I knew what was going on. I was smarter than the average 2 year old (I have Aspergers) and she said I was screaming and crying because I knew what Dad was trying to do. Dad apparently doesn't remember any of the bad things he's done to mom.

I can't consciously remember it, but I can remember things clearly from when I was just 3 years old. Is between 1 and 2 too early for me to be able to remember traumatic events like this? Could it be causing me psychological problems today? I dissociate at lot, and I have BPD, so I'm trying to figure out if that could be a repressed memory.

I do think things can be remembered from a very young age, they will always be foggy I think, always thinking did that happen or not?
I remember being put in the shed in a pram strapped in, I didn't like it. It was dark and dingy and there were spiders and webs. To have been in a pram I must have be very young.
To have a sociopath for a father was not going to make for an easy life. They like narcissists are prone to 'rewrite history' to suit themselves, hence the fact that he 'can't remember' any of the bad things he has done to your mother.
I dissociate too, I think its a numbing thing to block out things better forgot?? maybe.
