Other mistake: When Solomon Lane is being extracted out of the sunken truck there are two divers breaking in. However just a moment later only Benji surfaces with the prisoner while Luther is on the lookout on the rib. (00:55:11 - 00:55:36)
Other mistake: When Benji takes off the Wolf Blitzer mask, he continues to talk with the anchorman's voice until he takes off the voice altering tape too, but when Walker realises that he is not talking to Solomon Lane and proceeds to rip off the mask, Benji talks with his own voice without taking off the tape.
Answer: My understanding is Benji deliberately caused a collision with their cars so they can knock him out and make him think that he woke up in the hospital.
