The issue is that there are only so many protections for good samaratains. When a vehicle is on fire a person should be moved from it quickly. While the fuel tank should not explode there is plenty of gas, oil, and buildup of chemicals on the car to have smaller flareups and such. A burning car is enough to melt metal and thus a person should be moved as quickly and safely as possible. Though once out of the life threatening situation that person shoul not be touched without a license to do so as you open yourself up for lawsuit. Sad to know you cant help someone without threat of lawsuit but such is life these days till we have some form of reform in our judicial system to throw out these types of lawsuits.
