Even though I don't think the car analogy is a good one, I understand that just the fact that something can harm you doesn't make it inherently bad or unethical to use. You have enough control of your car to not kill yourself (or anybody else) as long as you drive responsibly, and take precautions. And the vast majority of people need to be teached not just about the technical aspects of driving but also about more common sense issues like why they should use their seatbelt or avoid driving under the effects of drugs, fatigue, etc. Some people (I guess I include myself here) think that LSD and other drugs can be used responsibly, too. Even though they don't have the obvious practical benefits of a car, the dangers related to their use can be significantly reduced if you take precautions and have an educated perspective. And just as with the car thing, nobody is born knowing how to safely use LSD. You need information, but that information is not readily available to most people at the moment. The internet or anectodical data are not good sources of information for this. So I guess that it may be a poor analogy, but the idea is that you can reduce the risk of using LSD to acceptable levels just as you can with a car.
