I'd like to see better photos so I could be certain whether that's a lateral rub or a longitudinal dent - but it looks like I'm going to take a contrarian interpretation here. It looks to me like a rear-to-forward dent, which given the reported impact orientations, could only have been caused by rearward motion of Vehicle 1. If Vehicle 1 were stationary and rubbed by Vehicle 2, I'd expect predominantly lateral scuffing and little or no forward denting. I suppose, however, Vehicle 2 could have turned somewhat more than is shown, so that its motion was more longitudinal?
Bottom line: if there's lateral scuffing, Vehicle 2 had to be moving. I don't think it's possible to completely rule out Vehicle 1 moving regardless. Depending on the appearance of the damage, it may be more likely than not that Vehicle 1 was moving.
