We (The US) have laws that hold people accountable for trespassing and theft, but I'm guessing you still lock your doors. A fundamental principle of engineering is protecting people from themselves, this is absolutely nothing new. Your life has been saved countless times because some engineer somewhere decided you didn't get to have a choice in something. (Maybe you like 50 ft falls, who are they to say that you should have to intentionally jump the handrail to hurt yourself?) It's Murphy's Law: if it's possible to do something stupid, somebody will and they might kill themselves and others in the process. So you make the stupid things hard to do. In this case the stupid thing to do is messing with a computing system that handles multiple mechanical and electrical systems where a misnamed variable or some mismanaged memory could be extremely dangerous. If you just have to tinker with something you can still buy/build a race car and take it to the track. Really, you should, it's fun.
