Lawdog

The Lawdog is a modified police vehicle used by the Sentinels. It can be unlocked by surviving 5 minutes in full RIOT mode in Lava Falls.

Inspiration
The Lawdog resembles a 1963 Ford Fairlane Police Car

Usefulness In-Game
The Lawdog is fast and nimble however it loses health very easily and will be attacked frequently due to it's Sentinel affiliation. It's not a very viable car to use as you get killed fairly rapidly while using it.
