How to unlock the Driving lessons achievement in Call of Juarez: The Cartel - Definitive Guide
You should be able to get anywhere from 2-5 people with the vehicle easily.
There are a few parts where there are a number of enemies to run over, specifically during the docks response, the motel chase after re-kidnapping Jesus and the desert chase with Juan (there are a lot of enemies who stand alongside the road).
If you don't get this by the end of the campaign, just reload one of these levels and run down some more guys.
You can pretty much obtain them on every chapter. Chapter 4 is your best option because it is right at the beginning of the level and has enough enemies to get this trophy. At the start of the chapter you will be in a vehicle and have to get to the docks. Once you reach the warehouse in the docks simply ram into the enemies and if you miss a few back up and redo. You will get a blue icon on the bottom right corner of the screen showing “Driving lessons x/10”, which will tell you of your progress. This trophy is cumulative and will probably get this way before the end of your first playthrough of the game.
As simple as it sounds, kill 10 enemies by running them over in your vehicle. There are numerous places where you will have opportunities to do this.
