"saw the parked car, and couldn't stop on time."

I would put it this way:

"saw the car parked, but I couldn't stop on time"

What do you think?

No, I think this is an explanatory note about an accident.
It's a series of consecutive events in the original:
turned --> saw car sitting there --> couldn't stop
If you insist, however, I can edit it.

Hi ollka,
if you are saying that the text is not in first person, "and" is Ok.
