No, sorry. This is way too big of an explosion of a mock up, and I don't think they'd park a mock up in the middle of the road either. It was long speculated that Ukraine uses the German Patriot system for those ambushes, since they're truck mounted, and this would definitely confirm it. So to me it seems pretty likely that it is indeed true. Ukraine moved it close to the front for ambushes and then got sloppy in keeping it save.
