Since its stop motion, you wouldn't see the morphing transition, they would wait for that to finish and then take the picture.

Not sure if that is what they actually did, but playing around with it a bit on my own it looks like you could get some decently fluid looking motion by taking screenshots of each "frame" that street view provides.

Have you actually used street view? I have never seen a street with less than 5-20 meters between each position.

According to a quick calculation that would give you a minimum apparent speed of 170 mph. (15 f/s * 5 m/f * 3600 s/h / 1600 mph/m/s)
