Hi Bridget,

I saw the video, it's pretty amazing.   But let's put in some numbers.

A good sprinter can achieve a speed of 40 km/hour which is ~ 11 meters per second.  The distance between the two car windows is around d = 1.8 meters.   So the time lapse between going in one and out the other is t = d/v =  0.19 seconds.   During that time the sprinter will fall a distance of h = gt2/2 = 0.175 meters. Here, g = 9.8 m/s2 is the acceleration due to gravity.   I presume he makes a bit of a vertical jump right before entering.  I don't see why he can't make it through. I'm sure I wouldn't make it, but then I don't think I would try
