I do not know about the other cars, but the collision where he hacked a w202 C class Mercedes is impossible!!! This alone makes the episode bad and unbelievable. Not only is the W202 steering hydraulic the brakes are aswell (and without SBC) and the car has no wireless antennas or tech except for a radio antenna!!! I'm not much of a hacker but I believe the radio antenna does not give you the access to the Engine Control Unit. If there wasn't for the Reid angle I would just turn the episode off and get on with the next one. If I wanted to see Sci-Fi I would watch Star Trek. This is just not acceptable.
