if something allowed him to propell himself forward suddenly with either constant force or a short burst of extreme force it is completely plausible for him to do this as car glass is built to shatter and grabbing someone along for the ride and landing on top of them is a common tactic in many martial arts
I mean, if he was a lead ball, he could, but humans are slightly more squishy and would be highly damaged by not one but 2 high speed collisions. Not to mention the fact that he grabbed the guy in the front seat, and somehow dodged the headrests, dashboard, etc
