I've done a couple myself. This one was taken on my phone, using one of its 'smart' camera features. I think it's actually done a pretty good job. It takes about ten rapid exposures and then uses that to determine what the moving object is in the frame. Then it isolates the moving part and applies a motion blur filter to the rest of the frame. As you can see, it's not bad, but not great. It's even had a reasonable go at the direction of blur which is pretty smart. Less impressive is the physical limitation of the technique, which gives two things that make this a dead giveaway as a 'fake'. The first is the shadow! The shadow of course moves with the car so the software thinks that it's part of the moving element. To a certain extent that's true, but the road beneath the shadow should be blurred, and of course it isn't. The second dead giveaway is the static nature of the wheels. They should be turning. Still, for a single click, no hassle solution straight out of the box I think it's a pretty good trick. :) I'm sure we're all familiar with the tracking motion shot. I've done a couple myself.
