Tell us about yourself!
Based of that logic I should never ride my motorcycle. People should never stay out of home and you should not leave home without a helmet. This method is not as bad as you think it is. Yes, you see horrible things and I appreciate your profession , however you cannot factor in the human error all the time. This method has certain risks, but if you are doing this with a small car, with hand break applied, and rock or wedge in from of rear tires, then is not that risky if you are smart about it.
