When Cyborg and Clark meet for the first time, Victor accidentally throws Clark into a wall using his left arm. The following x-ray by Clark reveals that Victor's left arm is the only body part that hasn't bionics in it.
Despite Lana's claims, a collision at 30 miles per hour is only fatal 45% of the time.
Regardless of the advanced technology possessed by LuthorCorp, it is not feasible to believe that they would go to the expense of using ultra-high speed cameras, capable of preserving video that can be viewed at 1/500th speed (500 frames per second), as simple security cameras. Even if one were to suspend disbelief, and acknowledge that LuthorCorp would spare no expense, and such cameras were used, the storage requirements, in hard-disk drive space in the case of CCD cameras, or inches of tape in traditional tape-based cameras, would become unfeasible too quickly to make it practical.
When Clark is confronting Victor outside the hospital, he demands to know how Victor destroyed his girlfriend's "Jeep", but she has actually been driving a GMC Envoy since the episode "Forever".
